A device for determining the shape and area switchtest objects contain optically coupled to the lens 1, the fiber optic Converter 2, the input ends of the optical fibers 3 which are located in the focal plane of the lens 1 in the form of a rectangular raster 4 arranged in rows and srica 8, the clock source 9.

The optical fibers of each of the raster column 4 are optically coupled through the respective electro-optical shutters 10 group photodetectors 5.

In addition, the device contains a group of shapers pulse 12, the outputs of which are connected with the first inputs of the group of elements AND IS NOT 13, the second inputs of which are connected with the direct output of the clock source 9, and the outputs to the inputs of the first binary adder 14, the inverted outputs the coding matrix 8 is connected, according to his discharge, with control inputs 11 group electro-optical shutters 10 corresponding columns of optical fibers 4 raster.

Gruppovogo 3, installed at a distance of fiber diameter from each other flush and fixed polymerizable substance in the conductive clips 39, with which the ends of the optical fibers 3 are covered with the deposited optically transparent conductive film 40, forming electrical contact with the sleeves 39, the space between the last determined by the height of the dielectric ring 41 is filled with the liquid crystal substance 42, forming together with the sleeves 39 of the liquid crystal shutter.

The device for determining the shape and area svetogorskogo object can be elucidated from the drawings, shown in Fig. 1 6.

In the proposed device for controlling electro-optical shutter is used, the effect of dynamic scattering of light, resulting in nematic liquid crystals 42 under the action of the applied control voltage supplied from the inverse outputs of the coding matrix 8 and exceeding critical for this crystalline substance is. Thus, in the initial state of the device at reset the pulse counter 7 for all electro-optical shutters 10 is supplied with a high voltage and they do not transmit the light.

When paadise in the focal plane raster 4 and can cause a blowout one, some or all of the fibers of the raster. The count of columns and rows of the raster is conducted so that the image seemed columns from left to right and the rows from top to bottom.

Synchronization of all nodes of the device is provided by clock pulses from source 9.

After turning on the power supply and the manual feed from block 28 of the triggering pulse is reset storage device 26 directly, and pulse counter 7, the first 34 and second 35 memory registers through the second element OR 23. Is the clock source 9 based on the same pulse through the first delay element 29. The pulses from the direct output of the clock source 9 start to arrive at the counting input of the counter 7, which starts counting of the number from zero. The appearance at its first direct binary output unit leads to the appearance of the first direct output coding matrix 8 positive pulse and the disappearance of such a pulse to invert the output of this matrix, which is connected with the control input 11 of the first electro-optical shutter 10. When this transition occurs between the liquid crystal 42 in the optically transparent state and an optical short-circuit is of Tolba raster 4.

In the result, the light signals attributable to the first raster column 4, propagating the optical fibers 3 (Fig. 1) will cause them to electrical signals at the outputs of those group of photodetectors 5, in which the optical fibers are light signals. If the output signal group of a sensor 5 reaches a threshold, the output connected to a pulse shaper 12 produces a signal of logical units otherwise, a signal of logical zero.

From the outputs of the pulse shapers 12 signals arising from the survey group of the electro-valves 10, received on the first input element group AND 13, the second inputs of which are also sequentially pulses from the clock source 9 (see diagram Fig. 3, where the digital indexes marked non block device). On the leading edge of each clock driver 33 generates the gate pulse supplied through the first element OR 22 on engraved control unit 20 entry, to the inputs of the least significant bits of which at this moment contains a binary number supplied with the direct outputs of the counter 7 and represents the number of respondents for the raster column represents the status of this raster column. All this information is recorded in the storage device 26.

The first pulse from the output of the pulse shaper 33, delayed in time by the second delay element 30, is fed to the enable input of the first memory register 34, the inputs of which the outputs of the second binary adder 15 is supplied binary count from outputs of the first binary adder 14. This number represents the number of units in the first column of the raster, as second input of the second binary adder 15 in this moment with the outputs of the second memory register 35 are zeros. It should be noted here that the first binary adder 14 has a pyramidal structure (Fig. 4) and outputs the generated binary number representing the sum of the units at the outputs of the groups of elements AND NOT 13.

Pulse, provided the entry state of the first raster column in the first memory register 34, a delay provided by a third delay element 31, is fed to the input recording resolution of the second memory register 35. This is done by overwriting the status of the first column in the raster of the first 34 and second 35 memory register.

Now, upon receipt of a control pulse from the coding matrix 8 on the second electro-optical satugo raster column 4. This number is supplied to the first group of inputs of the second binary adder 15, the first input of which is from the second memory register 35 receives the binary number corresponding to the number of units in the first raster column 4. In the second binary adder 15 these numbers are summed and, upon receipt of the second pulse from the output of the second delay element 30 on the entry permit the entry of the first memory register 34, it is recorded this amount, replacing there previously recorded the number of units of the first column of the raster). Once again delayed by the third delay element 31 of the second pulse is fed to the input recording resolution of the second memory register 35 and provides overwrite the content of the first memory register 34 (the sum of the units of the first and second columns of the raster 4).

In this way during the working cycle is the sum of the units of all the columns in the raster and recording the results of the addition in the second memory register 35. At the same time in the storage device 26 is consistently record the number of each of the columns of the image (in low-order bits of register storage devices) and the States of each column of the image (in the high-order bits of these registers). By the end of the cycle consistently say form svetogorskogo object, in the younger grades will be recorded the number of columns of the raster.

In the second memory register 35 to the end of the working cycle will be written to the binary number representing the number of units of all the columns of the raster. This number is supplied to the first group of inputs of block 21 of calculating the relative value of an area svetogorskogo object, to a second group of inputs which get stored in the third memory register 36, the number corresponding to the number of raster elements.

When a positive pulse on the latest direct output coding matrix 8 starts the timer 16, the pulse from the first output of which permitted the calculation in the block 21 relative magnitude square svetogorskogo object.

The signal from the second output of the timer 16 through the first element OR 22 provides the calculated value of an area in the storage device 26 and indication number corresponding to the calculated value, the indicator 24. The clock source 9 terminates simultaneously with the appearance of a positive pulse to direct the output of the last discharge coding matrix 8. This pulse coding matrix 8 is fed to the input of the off clock source 9 che the information of the operation of the clock source 9 is stopped and the counter 7. The pulse from the third output of the timer 16 provides zero through the second element OR 23 already stopped pulse counter 7, and the first 34 and second 35 memory registers.

When the pulse at the output of switch 18, provides a stop of the clock source 9 is delayed by the fourth delay element 32 for a period of time that overlaps the end of the pulse from the third output of the timer 16 (see diagram Fig. 3). The delayed pulse provides a reset cycle counter 17, the inclusion tsifropechatayuschee device 27 and the connection of the storage device 26 to transfer its contents to be printed.

The cycle counter 17 through the switch 18 provides off clock source 9 only through setting this switch, number of cycles, and then starts tsifropechatayuschee device 27. Multicycle operation of the device allows you to lock in the dynamics of changing the shape and area svetogorskogo object. In Fig. 6 presents the time variation of the shape and cross section sheet cover of the tree against the sky. For convenience, the location of the logical units of the high-order bits of the raster shaded and Maslova to right and top to bottom line by line.
