Abstract

The invention discloses a light path system for light beam tracking and pointing equipment. The light path system comprises an optical axis calibration system, an inner channel aberration correction system, an illumination laser emission system, a laser emission system and a fine tracking imaging system which are connected in sequence; according to the invention, the optical path system is used in a directional energy weapon, has the functions of inner channel aberration correction, optical axis calibration, target pointing and light beam emission. The optical path system can analyze aberration and distortion of a light beam through a Hardman detector and reference light, and performs real-time correction through a deformable mirror; so that optical axis calibration of an inner light path is realized through the fast reflecting mirror and the reference light, stable pointing to a target is realized through the fast reflecting mirror, laser emission is realized through the off-axis emission system, and illumination imaging and the like of a target are achieved through the illumination system. By means of the system, all-weather work can be achieved, and the system has the advantages of being high in optical transmission efficiency, tracking precision and aiming precision, high in light beam quality, high in environmental adaptability, high in space utilization rate and the like.

Description

technical field [0001] The present invention relates to the technical field of directed energy equipment, and more specifically, relates to an optical path system for beam tracking and aiming equipment. Background technique [0002] Beam control and tracking and targeting equipment (ATP for short) is an important part of laser directed energy equipment. The target is destroyed. [0003] The current existing technology has the following disadvantages: ATP equipment has a large structure, which is greatly affected by environmental changes in temperature and vibration, and the material is expensive, and the aiming accuracy cannot reach the arc-second level; when the high-energy laser is transmitted in the inner channel, The air is heated to produce a change in the refractive index gradient, which increases the aberration of the inner channel, deteriorates the beam quality of the light source, and reduces the damage capability of the system; the existing optical path cannot be ...
