matrix, an information compression unit, a microprocessor with program memory and an output module consisting of a liquid crystal digital matrix with a driver and a USB interface.

Closest to the claimed device is a "Device for measuring spherical coordinates", patent SU No. 1827136 of 03/11/91, MKI G 01 C, 3/00.

The disadvantages of this device, as an optical reconnaissance device, include the lack of the ability to memorize the image observed by the operator through the optical sight, which does not allow the implementation of the following tasks:

- documenting changes in the image observed through the optics of the device of the same observable area in time;

- the subsequent more detailed study on the display screen of the image observed by the operator, especially the image lasting a short time, for example, the launch of ATGM, the explosion of a shell, etc .; - transmission of the observed image to the intelligence gathering point;

- documenting the results of fire operations of combat formations;

- inclusion of the device in an automated system for recognizing enemy objects;

- the creation of remote reconnaissance eyes from command and observation posts hidden in the folds of the terrain.

In addition, the technical shortcomings of this device, namely, an electronic compass with an electronic elevation sensor, include a long time for its transfer from a traveling state to a combat state and vice versa due to the need to arrest it during movement and sizing during reconnaissance, as well as functional limitations possibilities of the magnetic compass when moving it over long distances (more than 100 km) from north to south (after moving it is necessary to carry out

routine work with the device to compensate for the vertical component of the magnetic field strength).

The purpose of the utility model is to increase the functionality of the device, improve its temporal characteristics and ease of use.

This is achieved by the fact that in the optical reconnaissance device, consisting of a laser rangefinder containing an optical sight, a control unit and a digital indicator, and a unit for measuring the magnetic azimuth and elevation angle, electrically and mechanically coupled to the laser rangefinder, an additional digital image storage unit mounted so that the optical axis of the optical sight included in the image storage unit is parallel to the optical axis of the rangefinder sight, while the photo indicator of the unit is located in the focal of the plane of the eyepiece of the digital indicator, the electronic device for processing and storing the image of this unit through the interface module is connected to the control unit of the laser rangefinder, and the unit for measuring the magnetic azimuth and elevation is made in the form of a triaxial electronic magnetic sensor, electronic tilt sensors of the magnetic sensor in two planes, a microprocessor with program memory calculating the magnetic azimuth, elevation angle (angle of deviation of the optical axis of the observation telescope relative to the horizontal plane bones), as well as non-volatile memory and a module that implements the RS-232 interface.

Figure 1 shows a functional block diagram of an optical reconnaissance device consisting of a laser rangefinder 1, a magnetic azimuth and elevation angle measuring unit 2, and a digital image storage unit 3.

The laser range finder 1 consists of a laser emitter 4, a laser emitting telescope 5, an ignition device 6, a control unit with controls and a secondary power source 7, an optical system for inputting a start signal into a laser photodetector 8, a laser photodetector 9, an optical observation telescope (visor ) 10, a digital indicator 11, an eyepiece for outputting digital information 12, a power source 13, and quotation optical wedges 14.

The laser emitter 4 is optically coupled to a laser emitting telescope 5, with an optical system for inputting a start signal 8 into a laser photodetector 9, electrically with an ignition device 6, a control unit 7, which includes controls and a secondary power source.

The control unit 7, which includes an output communication channel, for example, an RS 232 interface, is electrically coupled to an ignition device 6, a laser emitter 4, a laser photodetector 9, a digital indicator 11, an interface module 27 of an electronic image processing and storage device 15 of the digital memory unit image 3 and a unit for measuring magnetic azimuth and elevation 2.

The optical observation telescope 10 includes, as a component, a laser optical receiving unit 16 optically coupled to the laser photodetector 9, a sighting mark 17 and an eyepiece of the observation telescope 18.

The digital image storage unit 3 (FIGS. 1, 2) consists of a photo telescope 19, a photodetector 20, for example a CMOS with a controller, an electronic image processing and storage device 15, a photo indicator 24, for example a liquid crystal digital matrix

(LCD) with a controller 25, a high-speed output communication channel 26, for example, a USB interface, and a pairing module 27. The optical axis of the photo telescope is parallel to the optical axis of the observation telescope 10. The photo telescope 19 is optically-mechanically coupled to the photodetector 20, which in turn is coupled to an electronic image processing and storage device 15, consisting of an MJPEG information compression unit 21, non-volatile memory 22, a microprocessor with program memory 23. A photo indicator 24 is placed in the focus of the digital information output eyepiece mation of the laser range finder 12 and an electronic processing device and storing image 15 via the interface unit 27 is connected to control unit 7, a laser range finder.

The unit for measuring the magnetic azimuth and elevation angle 2 (Fig. 3) consists of a module of a triaxial electronic magnetic field sensor 29, electronic tilt sensors of the magnetic sensor in two planes 30, and a microprocessor with program memory 31 that calculates the magnetic azimuth (angle between the vector of the horizontal component of the magnetic field and the horizontal projection of the optical axis of the observation telescope 10), as well as the elevation angle (the angle of deviation of the optical axis of the observation telescope 10 relative to the horizontal plane). In addition, the electronic unit for measuring the magnetic azimuth and elevation includes a non-volatile memory 32 and a module 33 that implements the RS-232 interface.

The optical reconnaissance device operates as follows. The operator picks up the device in his hands and with the help of observation telescope 10 will search for the object. When an object is detected, it uses the controls of the control unit 7 to put the device in the photographing mode, directs the target mark 17 of the observation telescope of the device 10 to the object and photographs it using the photo telescope 19, photodetector 20 and the electronic device 15 of the digital image storage unit 3.

output digital information 12 device. The resulting digital photo is automatically stored in non-volatile memory 22 of the digital image storage unit 3.

After obtaining a digital image, the operator transfers the device to the mode of measuring the spherical coordinates of the object using the controls of the control unit 7, for which it directs the target mark 17 of the observation telescope 10 to the object and, using the controls of the control unit, starts pumping the laser rangefinder. Having received a signal from the digital indicator 11 that the laser emitter 14 is ready for radiation, the operator, using the controls, starts the emitter, while the laser pulse passes through the laser telescope in space in the direction of the object and through the optical input system of the start signal 8 starts the time counter. Upon receipt by the laser photodetector device 16 of the reflected laser signal from the object, the laser control unit 7 determines the time interval and calculates the measured range. Simultaneously with the range measurement, data from the magnetic azimuth and elevation angle measuring unit is interrogated. 2. The obtained data are displayed on the digital information indicator 11 and observed through the eyepiece of the digital information output of the device 12. Having received data on the range, the operator estimates them and, if necessary, changing using the controls of the control unit 7, the minimum measurement range of the object, makes repeated measurements of the range to obtain a reliable range. The obtained values of the spherical coordinates and the type of object set by the operator using the controls 10 are stored in the memory of the laser rangefinder control unit 7. Upon request from an external computer, the digital image of the object stored in the memory of the reconnaissance device, its type and spherical coordinates are automatically transmitted to the computer at the output device communication channel. The output communication channel of the device may include, for example, an RS-232 interface for transmitting a digital message and a USB interface for transmitting a digital image.
