Description

Laser target designator for attaching and detaching a concave lens bundle with lighting function

The present invention relates to a laser beam launcher capable of attaching and detaching a concave lens bundle performing an illumination function, and more particularly, attaching a detachable concave lens bundle to the exit of an infrared laser to illuminate the periphery of an object. It relates to a laser beam launcher that emits an infrared beam of the form.

One of the most popular gun attachment accessories in the 21st century is a laser target designator. A laser target designator is a device that uses a laser to direct a target so that it can aim a target using a laser or achieve a precise strike when supporting firepower from the air or the ground. Unlike aiming equipment, it implements the expected location of the impact point directly on the target, which is very helpful for quick aiming in case of emergency.

In the case of the U.S. military, the combination of a beam launcher and an optical sight is achieving significant results by applying it to the situation. In general, in terms of aiming precision alone, the scope, that is, the telescopic sight, is the best, but it is difficult to cope with multiple targets at close range.

In addition, when using a non-magnifying optical sight, it can be adjusted more quickly and accurately than aligning the line of sight using a conventional scale at close range. However, there was a problem in that sufficient time was required to align the crosshairs. Therefore, the laser beam launcher, which does not require line-of-sight alignment, can be usefully used in an emergency, and can be optimized and used in places with short engagement distances such as indoor and street warfare.

On the other hand, since the laser beam emitter uses a laser of an infrared wavelength that is invisible to the naked eye but visible with a night vision goggles, a non-visible laser beam emitter used together with the night vision goggles is used. This type of beam launcher is especially powerful when paired with Yashi Goggles, which are inconvenient to use the gun's aiming device.

However, the conventional laser beam launcher uses a beam having a small beam size in order to suppress the spread of the beam and increase the beam concentration on the target. Therefore, the detection and recognition of the surroundings of the existing light beam was limited, and in case of moonless moon, the amount of light entering the night vision goggles decreased and the search distance of the night vision goggles was shortened. On the other hand, in the case of a full moon with a large amount of light, shaded areas such as under trees or buildings in mountainous terrain generate shadows and are limited in detection.

The technology that is the background of the present invention is disclosed in Republic of Korea Patent Publication No. 0586830 (2006. 06. 08. Announcement).

The technical problem to be achieved by the present invention is to attach a detachable concave lens bundle to the exit of the infrared laser to provide a laser beam launcher that emits an infrared beam in the form of a searchlight so as to illuminate the periphery of an object.

According to an embodiment of the present invention for achieving this technical task, in a laser beam launcher capable of attaching and detaching a concave lens bundle performing an illumination function, a type of laser emitted from an infrared laser or a visible laser is selected, and the selected laser A light source control module for generating a control signal for adjusting the intensity and wavelength of a light source control module, a light source tube module including a visible light laser unit and an infrared laser unit, a direction adjustment module for controlling the irradiation direction of the output laser vertically, horizontally, horizontally, and the It is detachable from the light outlet of the laser beam launcher, and includes an auxiliary module for performing an illumination beam function when the infrared laser is emitted by a concave lens bundle when attached.

The infrared laser unit may include an infrared laser and a first convex lens bundle connected to the light source control module, and the visible ray laser unit may include a visible ray laser and a second convex lens bundle connected to the light source control module.

The auxiliary module includes an optical exit stopper formed to be detachably attached to the optical exit of the laser beam emitter, and a concave lens bundle formed on a portion of the optical exit stopper and connected to the first convex lens bundle when attached can do.

The light source control module may generate a control signal for operating the infrared laser unit when the illuminance is lower than a reference value, and may generate a control signal for operating the visible light laser unit if the illuminance is greater than or equal to the reference value.

The infrared laser unit may emit an infrared laser beam to a target object, and the visible light laser unit may emit a visible laser beam to the target object.

As described above, according to the present invention, by attaching a diffusion lens to the outlet from which the infrared laser beam is output, the output beam can be output in the form of an illumination beam, and the attached diffusion lens can be detached as needed from the outside of the laser beam emitter. Therefore, it can be installed in an existing laser beam launcher.

In addition, according to the present invention, since it is possible to output the infrared laser beam in the form of an aiming beam and an illumination beam, the detection distance is increased in a dark battlefield environment during night battle using the illumination beam, and shadows such as under trees or buildings in mountainous terrain are reduced. There is an effect that can perform the role of a searchlight that can search the surroundings in a specific area where it occurs.
