The invention relates to laser technology and is intended for shaping the laser information field for teleobiettivi, navigation and optical communications, control systems, automatic mobile devices. The invention can be used to control, landing and docking of aircraft, adjusting the trajectory of homing projectiles and missiles, navigation on challenging fairways, remote control robotic devices.

For the formation of the information field (PI) laser system teleobiettivi (LST) is a widely used method based on spatial encoding fields of light modulating pattern (UK application No. 1395246, Appl. 17.10.72,, publ. 21.05.75 year, NCI H4D, CL G01S 1/70). However, this method and apparatus, it implements inherent in significant light loss by modulating the raster, and the law encoding information field is determined by the type of modulation of the raster.

More perfect is a method based on element-by-element scanning the laser beam with a "needle-like" pattern (UK application No. 2133652, Appl. 14.11.83, No. 8330302, publ. 24.07.84,, CL F41G 7/00, NCI H4D; RU patent No. 2093849, priority, 13.12.1995, IPC G01S 1/70, 17/87). In this way, the laser beam performs a reciprocating scanned the e first one coordinate with a discrete transition in the orthogonal coordinate after each reciprocating motion of the laser beam, and then, after filling in laser radiation of a rectangular raster scan direction is changed to orthogonal. The selection of the coordinates of a managed object in IE LST is based on measuring the time interval between two received laser signals during the reciprocating scanning of the laser beam. Light loss when it is determined by the efficiency of the units (scanners), and the presence of a "needle-like" pattern of the laser provides a higher density of laser radiation than laser systems with spatial encoding fields of light modulating pattern and therefore a higher signal-to-noise in the photodetection device of the managed product.

The disadvantage of this method is the inability to transfer lsls additional information necessary for optimal management of object, which must be transmitted to the control object, regardless of its location in the information field. As such information can be, for example, command signals, changing the gain in the transmission path of the controlled object and the associated, for example, the angular velocity of the support, the movement of the line of sight, wind exposure, etc.

Closest to the claimed technical solution is the JV shall own, based on the sequential formation of two rectangular orthogonal information rasters formed by scanning the laser beam in each raster of N rows with the number of cycles of the scanning line is equal to three, with the specified delay between ticks, the opposite scanning two adjacent clock cycles and is equal to the time delay between the first and second rasters, after forming the P information raster form S command raster in which each step of the same direction of the scan line, the time interval between the first and second cycles is proportional to the magnitude of the transmitted command (patent RU №2099730, priority 01.03.1996, IPC G01S 1/70, G02F 1/11, prototype)

The disadvantage of this method is the increase in light loss and the decrease of the ratio signal/noise with increasing frequency information and command rasters. At higher frequencies decreases the time of forming the quantum of each line, and the time required Hasani laser beam on time delays between cycles of rows remains constant because it is determined by the method of forming the raster and technical characteristics of the equipment that implements this method.

The technical result of the invention is to increase the informativeness of the laser system teleobiettivi by increasing the hours which the notes repeat information and command rasters in the information field lsls by reducing the duration of the time delay between the cycles and reduce light loss.

The technical result is achieved by the fact that in the known method of forming FE LST, based on the sequential formation of the P pairs of rectangular orthogonal information rasters formed by scanning the laser beam in each raster of N rows with the number of cycles of the scanning line is equal to three, and the opposite scanning direction of two adjacent cycles, with a scan time quantum TWithand the formation's command rasters formed by scanning the laser beam in each raster of N rows with the number of cycles of the scanning line is equal to three, at which in each step the same direction of the scan line, the time interval between the first and second cycles is equivalent to the magnitude of the transmitted command, and the temporal delay between the second and third cycles, which is the characteristics of the raster type, different for each of the information and command raster simultaneously form two lines of the raster shifted relative to each other by N/4 rows, for that in turn form a single quanta in the first and then in the second row, and when forming the raster information, after forming the second beat of the second row, enter the time delay, which is indicative of a data frame, and the team rasters formed after the I first beat of the second row, enter the time delay δ t=0...TWithequivalent to the value of the transmitted command, after forming the second beat of the second row enter a time delay equal to the sum of the time delay - time delay, which is the sign of the command in the raster values (TWith-ΔT), and shift the next couple of newly generated strings are relatively formed of a pair of rows of N/4 rows.

The simultaneous formation of two rows of information in a raster shifted relative to each other by N/4 lines by alternately forming a single clock cycles in the first and the second lines, the introduction of a time delay, which is indicative of a data frame, after forming the second beat of the second row, the introduction after the formation of the first beat of the second row raster command delay time δ tK=0...TCequivalent to the value of the transmitted command, and the introduction after the formation of the second beat of the second row raster command time delay equal to the sum of the time delay - time delay, which is the sign of the command in the raster values (TWith-Delta tK), as well as shift the next couple of newly generated strings are relatively formed of a pair of rows of N/4 lines allowed us to enhance the usefulness of the laser system teleobiettivi by increasing the frequency of the forehand and the information field of the laser system teleobiettivi by reducing the duration of the time delay between the cycles and reduce light loss.

The applicant and the authors are not found in the patent and scientific literature lsls done in this manner.

Figure 1 shows the trajectory of the laser beam in the formation of two information (IR) (figa) and 1B)and one of the command staff (QC) (rasters) FE (pigv)) for the case of eight rows and three bars in each row. Figure 1 on the right or below the given line numbers (1 to 8), the left or above the given number of cycles (1 to 24), showing the spatial location of each quantum of rows (each row) in the corresponding raster, as well as the relative position photodetecting unit (FPU) of a managed object in a laser raster having coordinates of XToand YTolocated at the intersection of fifth horizontal and seven vertical rows. Three steps of scanning each line for easy image spatially separated. The linear sizes of frames equal to a×A.

Figure 2 presents the temporal plot of the position of the laser beam on the horizontal coordinate X (figa)and the vertical coordinate Y (figb)) in the formation of two information rasters containing eight rows. Left plots show the numbers of rows that define their spatial position in the raster. On the plots are the numbers of cycles (1 to 24), showing the spatial location of each of the second quantum strings in each raster.

On figa), 3b) and (3D) are shown timing diagrams of the position of the laser beam along the horizontal line 5 and the vertical line 7 information frames and the horizontal line 5 command frame, in which, according to figure 1, there are photodetecting unit (FPU) of a managed object. On figb), 3D) and 3E) are shown timing diagrams of the output pulses UFPUphotodetecting devices a managed object having coordinates of XToand YToin the laser raster and located at the intersection of fifth horizontal and seven vertical rows. Temporary plots the position of the laser beam on the line shows the number of clock cycles, forming strings used. For horizontal lines 5 a data frame that bars 13, 15 and 17. For vertical lines 7 a data frame that cycles 19, 21 and 23. For horizontal lines 5 team this frame bars 13, 15 and 17.

On figa) presents the temporal distribution of the laser beam along the horizontal coordinate in the formation of one more complex information in a raster containing 16 rows. Temporary plots the position of the laser beam on the rows and the position of the laser beam along the horizontal coordinate for each row when forming one raster information containing 16 rows, conventionally represented at figb) and figv).

The way the implementation of the is as follows.

When forming each of the information and command personnel of the laser beam form the bars, as shown in figure 1. Each cycle relative to the previous shifted by N/4=2 lines in the coordinate orthogonal to the direction of the scan line. After six cycles, for example 1...6, formed two lines, the first and second, spaced-coordinate is orthogonal to the direction of the scan line, also on N/4=2 rows. Then begins the formation of the next two lines of the third and fourth.

The scan time of each of the bars line the same and equal to TWith. In the formation of information frames the time delays TCin rows (2) shall be entered only after the formation of two cycles of two simultaneously generated strings. For example, simultaneous formation of the first and second rows IR (figa)) form 1, 2, 3, and 4 bars of the first and second rows, then extinguished the laser radiation at time TCand then 5 and 6 are formed bars of the first and second rows of IR. Delay values for IR with horizontal and vertical lines of different and equal, respectively, TPHand TPU. These values are characteristic horizontal or vertical frames. For each row in the temporary plot the position of the laser beam on the line (figure 2 and figa), 4B)consists of three so the and. The time delay between the first and second cycles is equal to TWith(because at this time, for example, the fifth row IR, according figb), between 13 and 15 cycles of the fifth row is formed tact 14 sixth row). The time delay between the second and third cycles is equal to (TWith+TPH) or (TWith+TPU). It is equal to the time TWithscan one measure to another row (for the fifth row IR is the formation of 16 quantum sixth line) and the time of extinction of the laser beam TPHor TPU.

During the formation of the command staff (pigv)), in which the direction of the scan cycles has the same direction, the first delay time δ tToin rows (damping of the laser radiation) (figd)) is introduced after the formation of the first stage of the two simultaneously formed lines and the second delay (TWith-Delta tTo+TPC) is introduced after the formation of two cycles of two simultaneously generated rows.

The repetition frequency of the command staff, usually 5-10 times less than the frequency of repetition of information frames. Command frames usually have two signs: one sign to pass amendments horizontally, and the second sign to pass amendments vertically.

Upon irradiation photodetecting unit (FPU) of a managed object located at the point PI with coordinates XToand YTo and located at the intersection of fifth horizontal and seven vertical rows (1)), the laser beam during line scanning FPU generates three pulses (figb), 3G), 3E)).

For information frames the time interval T1X,1Ybetween the first two pulses determines the coordinates of the FPU in IE, and the time interval (T1X,1Y+T2X,2Ybetween the first and third pulses is its sign (X or Y). The duration of the time interval T1X,1Ymay vary from TCup to 3TC. As follows from figa) and 3b), the total duration of T∑X, ∑Yintervals T1and T2for information frames is equal to: T∑X=(4TC+TPHor T∑Y=(4TC+TPU).

Command frame time interval T1Kbetween the first and second pulses determines the amount of transmitted commands δ tTo, the time interval (T1K+T2Kbetween the first and third pulses determines the sign of the command. For a command frame, the value of the time interval T1Kdoes not depend on the location of the FPU in IE and is determined by measuring the time delay δ tTointroduced during the formation of the first and second cycles time. The duration of the time interval T1Kcan change from 2TWithup to 3TWith. As follows from figd), the total duration of T∑Kintervals T1Kand T2Kfor the command frame is equal to T∑K=(5TWith+the PC).

The location of the FPU in FE relative to the center PI is determined, for example, the expression:where a is the linear dimension PI, T1X,1Ythe time between the first and second pulses FPU, TCthe scanning time of one beat of the string.

The value adopted additional commands Udcan be determined, for example, the expression: Ud=T1K-TWith=ΔTTo.

The sign of the measured coordinates XToand YToor command signal Udis determined by the time interval between the first and third pulses FPU, which for horizontal and vertical rows of a data frame or the command frame is equal to, respectively: (4TWith+TPH), (4TWith+TPUor (5TWith+TPC).

Delay values TPH,PU,PC, which are characteristic of horizontal information, vertical information or command frames, can be the following values: TPH=5 µs, TPU=15 μs, TPC1=5 µs, TPC2=15 μs, where TPC1and TPC2- the signs of the first and second command frame. The time interval δ tPSbetween adjacent signs for this example is equal to 10 μs. Because of the received pulses FPU fluctuant time, usually define the confidence interval of the reception signal. The length of time ogidan what I am receiving the third pulse characteristic Delta t PH,PU,PCcan be put equal to ±0,4ΔPSwith respect to the Central value.

Note that information about the position of the FPU in IE or transmitted biggest teams also found in the duration of the time interval between the second and third pulses FPU. The location of the FPU in FE relative to the center IP is determined by the expression:where a is the linear dimension PI, T2the time between the second and third pulses FPU, TWiththe scanning time of one beat of the line. The value adopted additional commands Udwhen measuring the time interval between the second and third pulses FPU, can be determined, for example, the expression:

Ud=2TC+TPC-T2K=Δ tTo.

When calculating the average values of the data defined by the time intervals between the first and second and between the second and third pulses FPU, standard error, obtained the averaged data will be reduced by approximately 1.4 times compared to single measurements, which increases the information content of the system teleobiettivi (Brewin. Theoretical foundations of statistical radio engineering. Book 1, M: Owls. radio, 1969, pp. 80).

Comparison of the proposed method and the prototype will perform on two criteria: the formation time of a data frame and loss of light monetize account the damping of the laser radiation on technological pause.

We define the time T∑2the formation of two rows of a data frame with three bars line with the original values of time intervals, which are described in the prototype:

the time of formation of the quantum line TWith=100 µs,

the time delay between the first and second cycles of the line T0=10 µs,

the time delay between the second and third cycles of the line TPH=20 µs,

the time delay between lines T6=10 µs.

After calculations, we get for the prototype:. The duration of the delay is equal to.

The formation of two rows of a data frame with three bars line in the proposed method, as follows from figure 2, is numerically equal to 6TWith+TPH. Assuming TWith=100 μs and TPH=20 µs, get the value of T∑2=620 μs and T∑detention.=20 μs. The resulting gain on the time of formation of the two strings and frame in General) for the proposed method compared to the prototype is the value of. After calculation, we get ηT=8,8%.

The amount of light loss can be estimated with the following expression: ηP=T∑detention/T∑2. Substituting the above values of the time intervals, we get:ηP=3%. The amount of light loss in the proposed way significant is but less than that of the prototype. Reducing light losses during the formation of the laser raster increases the signal-to-noise photodetector device managed object and, therefore, increases the information content of the system teleobiettivi.

In reality win much more. The time delay between the first and second cycles of the line must be chosen taking into account the inertia of the scanning system (vent) laser. So, when using acousto-optic deflectors from paratellurite for scanning the laser beam with the light aperture, as noted in the prototype, equal to 10 mm, the settling time of an acoustic wave is approximately 15 μs. Therefore, the time delay between the first and second cycles of the line to provide time resolution of pulse FPU from two adjacent cycles of the line shall be not less than 15 μs.

To increase the information content of the system teleobiettivi need to increase the refresh rate by reducing the time of forming cycles of the line. Considering the time of the formation of cycles of the line is equal to 50 μs and the necessary time T0=15 ISS will carry out calculations similar to the above. After calculations we obtain: ηT=18%, ηPFR=23%, ηP=6%. Upon further reduction of the time of the formation of bars line the payout will be more significant.

So the m way the simultaneous formation of two rows of information in a raster shifted relative to each other by N/4 lines by alternately forming a single clock cycles in the first and the second lines, the introduction of a time delay after the formation of the second beat of the second row, which is indicative of a data frame, the introduction after the formation of the first beat of the second row raster command delay time δ tTo=0...TWithequivalent to the value of the transmitted command, and the introduction after the formation of the second beat of the second command line raster, time delay equal to the sum of the time delay - time delay, which is the sign of the command in the raster values (TWith-Delta tTo), as well as shift the next couple of newly generated strings are relatively formed of a pair of rows of N/4 lines allowed us to enhance the usefulness of the laser system teleobiettivi by increasing the transmission frequency in the information field of a laser system teleobiettivi by reducing the duration of the time delay between the cycles and reduce light loss.

The invention also provides improved accuracy of selection of useful signals in two orthogonal coordinates with an increased frequency of formation of the laser system frame information field, which improves the accuracy of the orientation is a moving object and functional reliability of the control and correction of its path.

The method of formation of the information field of the laser system teleobiettivi based on the sequential formation of the P pairs of rectangular orthogonal information rasters formed by scanning the laser beam in each raster of N rows with the number of cycles of the scanning line is equal to three, and the opposite scanning direction of two adjacent cycles, with a scan time quantum TWithand the formation's command rasters formed by scanning the laser beam in each raster of N rows with the number of cycles of the scanning line is equal to three, at which in each step the same direction of the scan line, the time interval between the first and second cycles is proportional to the magnitude of the transmitted command, and the temporal delay between the second and third cycles, which is the characteristics of the raster type, different for each of the information and command raster, wherein simultaneously forming two lines of the raster shifted relative to each other by N/4 line, this in turn form a single the bars in the first and then the second row, and when forming the raster information after the formation of the second beat of the second row enter the time delay, which is indicative of a data frame, and when forming the raster command in the Le of forming the first stage of the second row enter the time delay δ t=0...T Withequivalent to the value of the transmitted command, after forming the second beat of the second row enter a time delay equal to the sum of the time delay - time delay, which is the sign of the command in the raster values (TWith-ΔT), and shift the next couple of newly generated strings are relatively formed of a pair of rows of N/4 rows.
