Description

Laser signal transmission device, laser system including the same, and laser signal transmission method {LASER SIGNAL TRANSFER APPARATUS AND LASER SIGNAL TRANSFER METHOD}

The present invention relates to a laser signal transmission device, a laser system including the same, and a laser signal transmission method.

Recently, various equipment using lasers have been developed in the military and communications fields. A laser interception weapon is a weapon that intercepts a target by radiating a laser signal directly to the target. Because it transmits the laser signal to the target at the speed of light, it can transmit the laser signal very quickly and transmit the integrated energy of the laser signal to the target. It is attracting attention as a means of clearing land mines or intercepting drones and missiles. In the case of communication using a laser, the characteristic of the laser that travels straight makes it possible to transmit and receive laser signals that cannot be eavesdropped.

Laser interception weapons make it easy to completely transmit the energy of the laser signal to the target due to the straight path of the laser, so it is possible to neutralize the target on the path where the laser signal is irradiated, but if there are obstacles in the path or the target is If it is not on the path, the laser cannot reach the target. In addition, in the case of laser communication, it is easy to completely transmit the laser signal to the receiving target due to the straight path of the laser, so if there are obstacles in the path or the receiving target receiving the laser signal is not present in the path. If not, the laser signal cannot reach the receiving target. Therefore, effective transmission of laser transmission in the military field, communication field, etc. is possible only when there are no obstacles on the path to the target or receiving object.
