In the device for aligning and checking the functioning of multichannel optical systems, a new set of structural elements, as well as the presence of connections between them, make it possible to carry out the alignment and verification of a multichannel system operating in different spectral ranges of wavelengths, to measure the range of the range-measuring channel of a multichannel system under real conditions of object detection and tracking , conduct self-control of parallelism of the sighting axes of the device channels.

The essence of the proposed technical solution is illustrated by drawings, where

Coordination of the pupils of the aligned multi-channel system is carried out using rhombic prisms (not shown) included in the device.

The device operates as follows.

Before starting work with the device, a parallelism of the sighting axes of the transmitting (FIG. 1) and receiving (FIG. 2) channels of the device is carried out, a self-monitoring of the integrity of the optical fiber and a self-monitoring of the parallelness of the ranging channel relative to the receiving and transmitting channels.

Self-control of the parallelism of the sighting axes of the transmitting and receiving channels is carried out as follows:

- establish a prism BkR-180 (not shown) for matching pupils of the transmitting and receiving channels of the device;

- set in working position a replaceable mirror 18, turn on the lamp 13;

- the image of the center of the diaphragm 12 is projected by the lenses 1 and 2 into the focal plane of the lens 2 by means of a spectrum splitter 15 and a mirror 14;

- set the emitter 5 or emitter 6 into working position;

- radiation from the emitter 6 or emitter 7 is projected into the focal plane of the lens 2;

- the image of the diaphragm 12 and the radiation of the emitters 6 or 7 are projected by lenses 8, 9 into the plane of the photosensitive area 10 of the electronic surveillance system;

- observe on the screen of the television monitoring system the image of the diaphragm 12, the image of the radiation body of the emitter 6 or emitter 7;

- the position of the sighting axis of the transmitting channel with the emitter 7 is controlled by the method described above when replacing the emitter with a caliber and its backlight.

Self-monitoring of the integrity of the optical fiber is carried out as follows:

- turn on the lamp 21;

- set the working mirror 18;

- the radiation from the lamp 21 enters the end of the fiber 3, passes the optical fiber and leaves the output end 4 of the optical fiber;

- the output end 4 of the optical fiber is installed in the working position, the image of the output end 4 is projected into the plane of the photosensitive area 10 of the electronic surveillance system.

With a whole optical fiber, an image of the luminous end 4 appears on the screen of the electronic monitoring system.

Self-control of the parallelism of the rangefinder channel relative to the transmitting and receiving channels is carried out as follows:

- include lamps 13 and 21;

- set the diaphragm 19. The lamp 21 illuminates the diaphragm 19;

- set the working mirror 18;

- the radiation from the lamp 21 enters the end of the fiber 3, passes the optical fiber and leaves the output end 4;

- the output end 4 of the optical fiber is installed in the working position, the image of the output end 4 is projected into the plane of the photosensitive area 10 of the laser radiation registration system 11 of the electronic observation system;

the plane of the lens 2. The centers of the images of the diaphragms 19, 12 and the center of the image of the end face 4 of the optical fiber should be aligned with the center of the electronic crosshair of the electronic surveillance system.

- adjust the 2nd channel of the multichannel system. By installing the 2nd channel, the center of the image of the diaphragm 12 is aligned with the center of the electronic crosshair of the 2nd channel of the multichannel system;

- make the adjustment of the 3rd channel of the multichannel system. The image of the luminous body of the mounted emitter by the lens 1 is projected into the plane of the photodetector of the 3rd channel of the multichannel system. By moving the emitter

devices in two mutually perpendicular directions determine the reception field of the 3rd adjustable channel;

- adjust the 4th channel of the multichannel system.

The radiation of the 4th channel of the multichannel system by the lens 2 is projected into the plane of the diaphragm 19.
