Description

Induction Sight

The utility model relates to the field of ontic instrument engineering, and more specifically to guided weapon guidance sights designed to create infrared radiation of high monochromaticity and low divergence, mainly for objects of armored vehicles.

A known aiming device 1, comprising a sighting channel including a lens and a reticle with a reticle located on its optical axis, a projection system and an eyepiece, a laser guidance channel including a laser emitter, a laser control field generation and conversion system and a lens, the lens being connected optically with a grid of the sighting channel and with a system for the formation and conversion of a laser control field by means of a spectrodividing element.

A disadvantage of the known sight-guidance device is the lack of a built-in control system for the parallelism of the control channel and the target channel, which complicates the alignment of the sight and leads to a decrease in accuracy using guided weapons.

The objective of the utility model is to increase firing accuracy when using guided weapons by providing control of the parallelism of the guidance channel and the sighting channel.

To solve this problem, the aiming device includes a sighting channel that includes an optically coupled lens, a first spectrodividing element, a reticle with a reticle, a projection optical system and an eyepiece, and a laser guidance channel that includes an optically coupled laser emitter, an optoelectronic system

the formation and transformation of the laser control field, the first spectrodividing element and the lens, while the lens and the first spectrodividing element are common for the sighting channel and the laser guidance channel, unlike the prototype, a reflector is installed, installed in front of the lens on its optical axis with the possibility of withdrawal from the course rays, an optical compensator installed between the optoelectronic system for the formation and conversion of the laser control field and the first spectrodividing element, and a de-camera, electrically connected to the monitor, the sensitive area of the video camera being optically coupled to the reticle plane of the grid by means of a second spectro-dividing element located between the grid and the eyepiece.

The introduction of a retroreflector mounted in front of the lens on its optical axis with the possibility of removing rays from the camera, a video camera electrically connected to the monitor, while the sensitive area of the camera is optically coupled to the reticle plane of the grid by means of a second spectro-splitting element located between the grid and the eyepiece, as well as the introduction an optical compensator installed between the optoelectronic system for the formation and conversion of the laser control field and the first m element, creates a sighting device with a built-in control system for parallelism of the laser guidance channel and the sighting channel, which provides the ability to control the parallelism of the guidance channel and the sighting channel of the sighting instrument under all operating conditions, and therefore the possibility of alignment of these channels, which leads to increase accuracy when using the guidance channel.

Figure 1 presents a schematic diagram of a sight-guidance device, figure 2 is a view of the field of view of the monitor at the time of monitoring the parallelism of the laser guidance channel and the target channel.

The sight-guidance device contains (Fig. 1) a sighting channel including optically coupled lens 1, the first

a spectrodividing element 2, a flat mirror 3, a reticle 4 with a reticle, a projection optical system 5, a second spectrodividing element 6 and an eyepiece 7, a laser guidance channel including an optically coupled laser emitter 8, an optoelectronic system 9 for generating and converting a laser control field, an optical compensator 10, a first spectro-splitting element 2 and a lens 1, while the lens 1 and the first spectro-splitting element 2 are common to the sighting channel and the laser guidance channel, the video camera And, the electronic connected with the monitor 12, the sensitive area of the video camera is optically coupled to the reticle plane of the grid 4 by means of a second spectro-splitting element 6 located between the projection system 5 and the eyepiece 7, as well as a retroreflector 13 mounted in front of the lens 1 on its optical axis with the possibility of output out of the rays. In objects of armored vehicles, the head part of the device 14 is also usually used, including a rotatable head mirror 15. The spectrodividing plane of the second spectrodividing element 6 in this implementation makes an angle of 45 ° with the optical axis of the sighting channel. The second spectrodividing element 6 can also be located between the grid 4 and the projection system 5. A flat mirror 3 is introduced for the convenience of the layout of the sight-pointing device. The optoelectronic system 9 for generating and converting a laser control field includes a scanning device, an optical signal coding system, and a pancratic system 2. Optical

the compensator 10 is designed to compensate for the non-parallelism of the axes of the sighting channel and the laser guidance channel and can be made in the form of a block of rotary wedges or movable in two mutually orthogonal lens directions. As a retroreflector 13, a triple prism or a cat-eye system including a lens and a flat mirror located in its focal plane can be used. Spectro-splitting elements 2 and 6 provide transmission of laser radiation from the guidance channel and reflection of visible radiation with high coefficients close to 1.

Aiming device works as follows.

The gunner fires with guided missiles, observing through the eyepiece 7 and holding the reticle of the net 4 on the target after launching the missile until it is hit. If it is necessary to check the parallelism of the laser guidance channel to the sighting channel, the gunner introduces the retroreflector 13 using the special mechanism (not shown in Fig. 1) and starts the laser emitter 8 of the laser guidance channel, having previously set the minimum control field value using optoelectronic system 9 of the formation and conversion of the laser control field. The infrared radiation of the laser emitter 8 passes through the system 9, the optical compensator 10, then the first spectro-splitting element 2, the lens 1, is reflected from the retroreflector 13 and returns to the lens 1. Then it is partially reflected from the first spectro-splitting element 2 (a few percent), is reflected from the plane mirror 3 and illuminates the reticle of the grid 4 of the target channel. Next, the laser radiation passes through the projection system 5, the second spectro-splitting element 6 and enters the video camera 11, forming the image of the laser control field. On the screen of the monitor 12, the image of the reticle 16 (FIG. 2) is observed against the background

FIELDS of control 17. If the aiming mark 16 is shifted relative to the center of the image 17 of the control field, this means that the laser guidance channel is not parallel to the sighting channel. Violation of the parallelism of the channels is inevitable with prolonged mechanical stress (shock, vibration), as well as with significant changes in ambient temperature. At the same time, missile guidance errors are inevitable. If we combine the reticle with the center of the image of the control field using the optical compensator 10, then the laser guidance channel will be parallel to the sighting channel and when using the guidance channel to fire a guided missile, shooting errors will be eliminated.

Thus, the aiming device-target provides the ability to control the parallelism of the laser guidance channel and the target channel and the ability to align these channels, which provides a solution to the problem of increasing firing accuracy when using guided weapons.
