 Electro-optical amplifier of electrical signals / 2402158
Electro-optical amplifier (EOA) has a detecting element (DE) with a mirror surface whose spatial position varies under the effect of electrical signals (ES), wherein terminals for connection to the electrical signal detecting element are the input of the EOA, a plate with a mirror surface which faces the detecting element, an optical source directed at the mirror surface of the plate or detecting element, and a photodetector whose output is the output of the EOA. The principle of operation of the EOA is based on conversion of an electrical signal to spatial oscillations of an optical beam using the detecting element, amplification of these oscillations and their conversion to an electrical signal using the photodetector. The detecting element used can be a piezoelectric plate for example. Amplitude gain of spatial oscillations of the optical beam takes place during its propagation between the detecting element and the mirror plate through successive reflection from each one of them. High amplification factor is provided by multiple reflection of the optical beam from the oscillating detecting element.
 Method of electric signals amplification / 2400012
Method for amplification of electric signals consists in their conversion into spatial oscillations of optical beam, amplification of these oscillations by amplitude and conversion into electric signal. Conversion of electric signals into spatial oscillations of optical beam is carried out with the help of piezoelectric plate with mirror reflecting surface. In order to amplify spatial oscillations of optical beam by amplitude, plates may be used with mirror reflecting surfaces facing each other. Such amplifier does not contain active and passive radio elements, therefore its pass band is practically unlimited, and in case of high accuracy of mirror surfaces, its non-linear distortions are insignificant. Besides it does not have stability limit and may provide for high amplification ratio, without change to self-excitation mode. Conversion of spatial oscillations of optical beam into electric signal is carried out by means of correlation treatment of optical radiation at entrance pupil of photodetector.

FIELD: physics. SUBSTANCE: apparatus has, arranged in series on the beam path and optically connected, a laser, a collimator, an acoustooptic and a piezoceramic deflector, a lens, a coordinate table, as well as a computer. The lens is directed onto the labelled article. The coordinate table consists of a movable part and a drive. One of the computer inputs is the input of the apparatus. The other inputs are connected to outputs of the piezoceramic deflector and the drive of the coordinate table, and the outputs are connected to inputs of the acoustooptic and piezoceramic deflectors and the coordinate table. An electromagnetic deflector is placed between the piezoceramic deflector and the lens. The input and output of the electromagnetic deflector are connected to the corresponding input and output of the computer. A box with labelled articles is mounted on the movable part of the coordinate table. The articles lie in the focal plane of the lens.

EFFECT: high efficiency of the laser labelling apparatus and shorter time for placing the articles into the working area. 2 cl, 1 dwg
The invention is a laser processing equipment designed for marking of industrial products. Known laser marking, which comprises a laser, a collimator, two electromagnetic deflector lens group marked products placed on the table within a working area defined by the baffle and lens, as well as the computer, one input of which is the input set, the other two are connected to the outputs of the deflection unit, and outputs connected to inputs of the latter [1]. The advantage of this setup compared to non-laser equipment - the ability to create distinct and save the image on the products of any size and of any material. This image can be graphical, grayscale, three-dimensional (inside transparent materials) and to incur any personal information. World production of such plants is several thousand pieces per year, and they are used for marking the most elite products. The main disadvantage of these installations, which prevents their use for marking products for mass production, is a great time drawing the image: T≥Nτ~10, where N is the number of pixels (image points), which determines the image quality, τ - continuous the straps electro-mechanical deflectors, which is measured in hundreds of microseconds. In one hour such installation can be marked only a few hundred products. The closest to the invention is a laser device, comprising sequentially disposed along the laser beam and optically coupled laser, acousto-optic and piezoelectric deflector, lens, groups of marked products, placed on a two-coordinate table so that the marked surface of one item is within the working area of the lens, and marked the surface of other products can be introduced into this zone by the movement of the coordinate table, and a computer, one input of which is the input set, and the other three are connected to the outputs of the position sensors deflectors and a coordinate table, and outputs connected to inputs of deflectors and a coordinate table [2]. This setting differs from the similar use of acousto-optic and piezoelectric deflectors light, small deflection angle which allows you to create a working field, which is placed only one item. The second difference is the use of two-coordinate table, which complicates the installation, but provides the ability to relatively quickly change the items in the work area. The advantage of this setup compared to similar - su is the natural enemy less time marking one product - about one second, which allows you to mark about 3 thousand pieces per hour and expands the number of potential consumers. The slow shift of the marked items in the work area using a two-coordinate table, which takes much greater time than the application of a marked image by using acousto-optic and piezoelectric deflectors, in addition, the high cost of two-coordinate table increase the cost of installation. The performance and cost of such installation does not satisfy consumers and creates a barrier to its mass production. The task of the invention is to bring the performance of laser marking to the energy limit is determined by the laser power, the size of the light beam in the focus of the lens and the sensitivity of the marked surface, dramatically reducing the time the goods are installed in the working area. The goal of the project is achieved in that the laser marking, which includes successively arranged along the beam and optically coupled to the laser, collimator, acousto-optic and piezoelectric deflector, lens, aimed marked on the product, compound table, consisting of a movable part of the actuator and the computer, one entrance is in which is the input set, other inputs connected to the outputs of the piezoelectric deflector and a coordinate table, and outputs connected to inputs of acousto-optic and piezoelectric deflectors and a coordinate table, between the piezoelectric deflector and the lens is mounted an electromagnetic deflector, input and output of which are connected with the respective input and output of the computer and on the movable part of a coordinate table locked box marked products, located in the focal plane of the lens, the box contains cavities, the size of which corresponds to the dimensions of marked products. In addition, the installation of a used single-axis drive table. The essence of the proposed technical solution is that the move operation work zone setup from one product to another, which in the prototype is performed using a two-coordinate table, this installation is performed by an electromagnetic deflector and single-axis drive table that allows you to replace about 90% of the table movement to move the mirror electromagnetic deflector and dramatically reduce the time spent on the change of position of the working area. In addition, the proposed invention allows to reduce the time for installation of products in the work area through the use of boxes in which Phi is serwotka marked product, since this makes it easier to change from one batch to another. In the result of the task to bring the performance of laser marking to the limit determined by the energy of the process laser writing. The proposed solution allows you to develop laser marking almost any performance required for a specific user (up to several products per second, by varying the laser power and the size of the focused beam. Figure 1 shows the layout of the laser marking, where: 1 - laser; 2 - collimator; 3 - acousto-optical deflector; 4 - piezoelectric deflector; 5 - electromagnetic deflector; 6 - lens; 7 - marked product; 8 - box; 9 - the movable part of a coordinate table; 10 - axis drive table; 11 - computer. The laser marking consists of optically coupled laser 1, a collimator 2, the acousto-optic deflector 3, the piezoelectric deflector 4 and the electromagnetic deflector 5, lens 6 and marked articles 7, placed in box 8, which is fixed on the movable part of the XY table 9, mechanically associated with single-axis drive table 10, and includes a computer 11, one input of which is the entrance mouth is ovci, the other three are connected to the outputs of the piezoelectric deflector 4 and the electromagnetic deflector 5 and the axis of the drive table 10, and outputs connected to inputs of all of the vents and single-axis drive table. The design of the box 8 provides the location of marked products 7 in fixed positions, for example, contains cavities, the size of which corresponds to the dimensions of products. The design of the movable part of the XY table 9 provides the installation box 8 in a fixed position, for example, contains a recess, the size of which corresponds to the size of the box 8 and the dimensions of the box and these recesses provide the location of marked products 7 in the focal plane of the lens 6. The scanning plane piezoelectric deflector 4 and the electromagnetic deflector 5 are perpendicular to each other, and the image plane scanning acousto-optic deflector 3, which is created by the mirror (position shown) piezoelectric deflector 4, coincides with the scanning plane electromagnetic deflector 5, that is, the acousto-optic deflector 3 and the electromagnetic deflector 5 scan radiation in one plane. The design of acousto-optic, piezoelectric and electromagnetic deflectors are described respectively in [3-5]. Installing the laser marking is as follows. The party marked products 7 download and record in box 8, establish and fix the box on the movable part of the XY table 9, via the input set to the computer 11 enter the program image recording and give commands to start marking. All subsequent processes are running on the target system. The radiation of the laser 1 is converted by the collimator 2 into a parallel beam, which passes acousto-optic deflector 3, the piezoelectric deflector 4, the electromagnetic deflector 5 and is focused by lens 6 in field marking one of the marked products 7. Acousto-optic deflector 3 forms a portion of an image consisting of pixels in a section of straight and piezoelectric deflector 4 then moves the laser beam in one step grid in the perpendicular direction. Alternating these steps, acousto-optic deflector 3 and the piezoelectric deflector 4 mark the item 7. Next, the electromagnetic deflector 5 moves the laser beam 1 in the marking of the next product, and the process repeats. The alternation of processes of image formation and change of field marking allows you to mark the number of items located within the scanning plane electromagnetic deflector 5. After applying images within one series Mar the dummy products 7 one-axis actuator of the table 10 moves the movable portion of the XY table 9 on the distance between rows in box 8, that allows the marking of the entire batch of products placed in the box. The last step is removing the box with a coordinate table. The feature of this laser marking is that the time spent on processes not associated with the interaction of laser radiation with marked product, comprise a small part of the duration of its operation. Therefore, its maximum performance - several items in the second, several thousand pieces per hour and about a million products per year. The proposed setup allows you to mark any industrial products, creating high-quality, well-stored graphical, grayscale, color and three-dimensional images. A small number of such plants can provide the labeling of all products of the highest performing industrial enterprise or multiple enterprises. The relatively low cost of marking one product, determined by the ratio of the cost of the installation and its operation to the number of marked products for life, allows you to extend the scope of this installation.
