Description

Aiming point holding device for laser weapon and portable laser weapon having same

The present invention relates to a device for maintaining an aiming point for a laser weapon and a portable laser weapon having the same, and more particularly, to maintaining an aiming point for a laser weapon that can strike a laser beam for continuous striking at a point on a target by maintaining the aiming point in a laser weapon The invention relates to a device and a portable laser weapon having the same.

In general, a laser weapon is a weapon system of a new concept that rapidly strikes a target by focusing a laser beam on a target.

Laser weapons deliver energy to the target at the speed of light, unaffected by gravitational fields.

The laser weapon, a directional energy weapon, is being developed as a new concept weapon that can change the paradigm of warfare in future warfare with the characteristics of non-linear and small-scale distributed combat, non-lethal warfare, non-contact and remote proxy warfare, and space warfare. .

In particular, high-energy laser weapons are in the spotlight as a method for intercepting a large number of drones and unmanned aerial vehicles infiltrating from a distance.

Moreover, compared to conventional weapons, laser weapons have less incidental damage in the process of intercepting targets, so continuous development is expected as a safe and clean future weapon.

Laser weapons are mainly developed as large, high-power laser weapons mounted on platforms such as trailers or ships and airplanes in order to secure the power to strike and destroy the target. Therefore, the need for the development of small laser firearms used as weapons is gradually increasing.

In order to improve the effectiveness of laser miniaturization, it is important to continuously fire a laser at a target point, that is, to continuously fire a laser beam at a single point to transfer the heat of the laser beam.

However, it is impossible to mount a camera for image measurement and a computer for image processing because the large, high-power laser weapon mounted on the platform maintains the aiming point through the image based on image tracking/aiming, and in the case of a portable laser small firearm, it must be carried by an individual. There was one problem.

Therefore, a portable laser small firearm is mounted and operated using a cradle such as a bi-port or a tree port to maintain the aiming point, and there is a problem that at least two people must operate it due to the weight of the cradle such as a bi-port tree port for aiming.

In addition, since the portable laser small firearm must be used after being mounted using a cradle such as a bi-port tree port, it is very difficult to respond immediately when a target is found.
