Abstract

FIELD: physics.

SUBSTANCE: light spot formation on the target is produced with a beam consisting of, at least, two colours, the combination of which gives an impression of a colour corresponding to the target colour in the spot zone. The emission perception reflected from the target is carried out through a filter of one of the combined colours. A portion of the reflected radiation is passed through the filter, emanating primarily from the spot. The combined colours are formed by sources having emission spectra corresponding to the wavelengths of these colours, respectively.

EFFECT: expanding the functionality, providing concealed aiming.

Description

The invention relates to the field of military equipment and can be used in small arms with laser guidance systems.

The prototype is a laser pointer, consisting of an emitter including a housing, the surface of which has a spherical portion, a mechanism for fixing the emitter in the target housing, an alignment device, a battery pack, while the target housing has a spherical support portion for contacting the rear of the spherical surface of the emitter housing, and the locking mechanism is made in the form of a washer with a clamping nut, while the inner surface of the washer is made spherical for contacting with the front of the surface of the emitter housing [Pat. RF 2253822, IPC F41G 1/32, 2005].

The disadvantage of the prototype is the limited functionality due to the lack of the ability to imperceptible (secretive) aiming. It should be noted that covert infrared aiming requires sophisticated night vision equipment and complicates the observation in the presence of high-temperature radiation sources near the target.

The objective of the invention is to expand the functionality and simplify the design.

The problem is solved in that in the method of aiming by a laser emitter, which includes the formation of the last light spot on the target and the reception of reflected radiation from it by the receiver, the spot is produced by a beam consisting of at least two colors, the combination of which gives the impression of a color corresponding to the color of the target in the spot zone, and the perception of reflected radiation is carried out through the filter of one of the combined colors.

A part of the reflected radiation, mainly emanating from the spot, is passed through the filter. Combined colors are formed by sources having emission spectra correspondingly equal to the wavelengths of these colors.

These distinctive features allow you to achieve the following advantages compared with the prototype.

The formation of a spot by a ray consisting of at least two colors, the combination of which gives the impression of a color corresponding to the color of the target in the spot zone, and the perception of reflected radiation through a filter of one of the combined colors allows, using the features of the visual apparatus, to conduct covert aiming, since the color a spot is perceived by the naked eye close to the color of the target, and the adversary may therefore not notice this spot and, therefore, not take any retaliatory action. In this case, the filter removes one of the colors from the radiation reflected from the target and makes the indicated spot stand out against the background of the target, which allows the shooter to aim.

Passing through the filter part of the reflected radiation, mainly coming from the spot, allows you to not distort the color of the other part of the target observed by the shooter, which improves the aiming conditions.

The formation of compatible colors by sources having emission spectra correspondingly equal to the wavelengths of these colors simplifies the design.

The invention is illustrated in the drawing.

The drawing shows a device for aiming a laser emitter.

The device for inconspicuous aiming comprises a laser emitter 1, emitting, for example, a two-color beam 2 into the target 3 and connected through the shaper 4 to the pulse generator 5, and an optical sight 6 with a filter 7.

The device operates for inconspicuous aiming as follows.

Suppose the enemy’s target is bottle green. To obtain targets of this color on target 3, it is necessary for the emitter 1 (for example, a two-color LED) to emit (simultaneously or alternately) yellow and blue rays to obtain a two-color beam 2. For this, the shaper 4 sets the required quantitative content of the combined colors, for example, by changing the duration of the electrical pulses coming from the generator 5, and their duty cycle regulate the intensity (brightness) of these colors. After selecting the desired (bottle green) color and its intensity, beam 2 is directed to target 3 and the radiation reflected from the spot is observed through the filter 7 of the sight 6. Filter 7 removes one of the combined colors, for example blue, which allows the shooter to observe the spot on the target (which for the enemy remains invisible) and carry out aiming.

The implementation of the invention will allow you to create a simple device that provides inconspicuous (secretive) aiming.
