Description

The invention relates to means for controlling sights intended for tele-orientation in the optical beam of machines, in particular aircraft, using infectious lasers as radiation sources.

Monitoring the parameters of the sight, for example, such as misalignment of the sighting and emitting channels, the type of direction-finding characteristics, the magnitude of the control field, etc., is a complex technical task requiring special technological equipment that provides accurate control parameters. High accuracy of adjustment and control of the parameters of the sight allows you to ensure its desired performance. One of the main requirements for control is the high accuracy of aiming the aiming mark at the aperture opening, the angular size of which corresponds to the angular size of the photodetector of the aircraft at maximum range.

A device is known for monitoring the parameters of the sight of a television orientation system with radiating channels on infectious lasers, containing a diaphragm with a hole in the center, which is located in the focal plane of the collimator lens, a photodetector (FPU) with electronic equipment, an optical bench, a light source, a cassette with light filters, electronic and instrumentation coordinates. This device is selected as a prototype [1].

The disadvantage of this device is that the determination of the quality of the device and deviations from the Z and Y coordinates is based on a subjective assessment of the accuracy of the aiming mark of the sight in the diaphragm hole, as a result of which the measurement results may differ from each other, which requires repeated measurements to determine the average value .

The objective of the invention is to improve the quality control of the parameters of the sight by ensuring maximum accuracy of combining the aperture of the diaphragm with the aiming mark with high adaptability and simplicity of the design of the device.

The solution to this problem is achieved by a device for monitoring the parameters of the sight of a tele-orientation system with radiating channels on infectious lasers containing a diaphragm with a central hole located in the focal plane of the collimator lens, a photodetector with electronic equipment, a cassette for filters, an optical bench and coordinate measurement and separation equipment, in wherein the diaphragm, cassette and photodetector are placed on a two-coordinate table equipped with a photoelectric converters (FEP) and brackets connected to a stand installed in a reader mounted on an optical bench, while the electronic equipment of the photodetector is placed between the brackets by means of an adapter, on the end of which a U-shaped groove is made with stop elements included in it from both sides, in contact with the liners placed inside the groove symmetrically relative to the rack, and the coordinate extraction equipment is connected to the electronic equipment of the photodetector by means of an appar coordinate measuring stages.

Placing the diaphragm, cassette holder and FPU on a two-coordinate table equipped with photovoltaic cells and brackets makes it possible to simplify the design of the device, mounting and dismounting the device at minimal cost, and increasing the accuracy of combining the diaphragm hole with the crosshair of the reticle.

The presence of a rack, a reiter mounted on an optical bench, ensures the speed of alignment of the paired axes of the device, and the fastening of the FPU electronic equipment through an adapter in which a U-shaped groove is made to accommodate the inserts, allows the device to be moved along the height of the reiter’s rack together with the cassette, FPU and FEP.

Figure 1 presents the control circuit parameters of the sight, where:

1 - a sight of a television orientation system with radiating channels on injection lasers;

2 - a collimator with a lens that allows you to artificially create an infinitely distant object (aperture, scale, world, etc.);

3 - diaphragm with a hole in the center;

4 - cassette holder for filters 5, the transmittance of which is selected from the conditions for equalizing the signals generated by different channels of the sight on the photodetector;

6 - photodetector (FPU) with a hole mounted on the mating axles 7;

8 - two-coordinate table with photoelectric converters (PEC);

9 - electronic equipment of a photodetector;

10 - electronic equipment for measuring coordinates;

11 - instrumentation for the allocation of coordinates;

12 - optical bench;

Z and Y are the coordinates characterizing the position of the beam relative to the axis of sight.

Figure 2 presents the device of the two-coordinate table with photoelectric converters, on which the installation of component devices for controlling the parameters of the sight is carried out, where:

13 - bed, on the guides of which the raider 14 moves with the latch 15. The position of the reiter on the guide is counted along the line 16;

17 - clamp, with the help of which the rack 18 is fixed on the reiter;

8 - two-coordinate table (Z, Y) s (FPU);

19 - dial, which controls the angle of rotation of the table;

20 - screws, with the help of which the installation of a two-coordinate table 8 with photoelectric converters 21 in height on the rack 18 is carried out using brackets 22 with clamps 23.

Figure 3 and 4 shows the fastening of the electronic equipment of the photodetector to the rack of the two-coordinate table with photomultiplier, where:

24 - adapter, in which the electronic equipment of the photodetector is fixed on the rack 18 of the two-coordinate table 8 with an electron beam converter 21;

25 - liners placed in the groove 26 of the adapter 24, which has locking elements 27 in contact with the liners, symmetrically placed relative to the rack 18 of the two-coordinate table 8. For example, for fixing on the liners can be made grooves 28, which contact the locking elements .

The operation of the device is as follows: the sight device 1 is mounted on an optical bench 12, the diaphragm 3 is installed in the focal plane of the collimator lens 2 together with a cassette 4 with light filters 5 and a photodetector 6. All this is attached to a two-coordinate table 8 with photoelectric converters 21. Electronic the apparatus 9 of the photodetector 6 is installed in the adapter 24, having an U-shaped groove 26 at the end, into which the inserts 25 are made, the height of which is the size of this groove. The liners 25 cover the rack 18 of the two-coordinate table 8. The adapter 24 is installed between the brackets 22 on the opposite side of the table, and the adapter has locking elements 27, which, in contact with the liners 25, compress them to the rack 18 and fix the adapter 24 with electronic equipment 9 of the photodetector 6. Electronic equipment is electrically connected to the photodetector and control and measuring equipment for measuring 10 and the allocation of 11 coordinates Z and U.

After the device is connected, the diaphragm hole is aligned with the crosshair of the aisle crosshair, then the radiation signal is recorded by the recording device 10 and the deviations of the coordinates from the optical axis due to linear movements of the two-coordinate table by rotating the drums of the photoelectric converters 22 are brought to the zero position, and the mating axes 7 are aligned height is produced by moving the device on the rack 18.

The device allows to improve the quality of control of the parameters of the sight by ensuring maximum accuracy of combining the aperture of the diaphragm with the aiming mark with high manufacturability and simplicity of design.
