Front directly-correlated light beam pointing feedback device

Abstract

The invention discloses a front directly-correlated light beam pointing feedback device, which comprises a sampling mirror, a reflector, an optical system, a drop point sensor and a data processing system, wherein the sampling mirror is arranged in a direction of a to-be-emitted light beam. According to the device, pointing information of the emitted light beam is obtained through the data processing system, and the information is fed back to a control system for control, so that the emitted light beam of a high-energy and high-power laser system can be ensured to hit a target accurately.

Description

technical field [0001] The invention relates to beam pointing control, in particular to a pre-directly related beam pointing feedback device. Background technique [0002] In high-energy, high-power laser and general laser research, the beam pointing control system is usually designed to control the beam propagation direction, especially in high-energy, high-power laser systems, due to the high precision requirements for beam propagation direction control, the system structure is complex , a small pointing deviation will lead to deviation from the target on the target surface of the beam after long-distance transmission. With the development of high-energy and high-power laser technology, in some special applications, it is not possible to set the landing point feedback on the target surface of the beam or the downstream of the target surface, but can only rely on the stability of the emission system itself to ensure the accuracy of the beam aiming. This leads to the incomp...

Problems solved by technology

With the development of high-energy and high-power laser technology, in some special applications, it is not possible to set the landing point feedback on the target surface of the beam or the downstream of the target surface, but can only rely on the stability of the emission system itself to ensure the accuracy of the beam aiming. This leads to the incomplete closed loop of the aiming process, and serious cases will lead to miss

For example, in the application of laser weapons, if the last reflector is deformed or displaced due to its own or external force, resulting in the deflection of the beam emitted from the last reflector at the launch end, because the existing technology cannot obtain the beam passing through the last reflector After the pointing, causing the beam to deviate from the preset target
