Abstract

The invention discloses an array light beam emission and imaging integrated device and system and a use method thereof, the device comprises an aperture diaphragm, a plurality of light beam emission and imaging sub-modules and an optical synthesis imaging unit, and the aperture diaphragm is provided with a plurality of sub-apertures; each light beam emission and imaging sub-module comprises light path units arranged in one-to-one correspondence with the sub-apertures, light splitting units arranged in one-to-one correspondence with the light path units, and laser emission units arranged in one-to-one correspondence with the light splitting units; and the optical synthesis imaging unit is used for coherently synthesizing the light transmitted by all the light splitting units to form an image. According to the invention, effective imaging identification of long-distance weak and small targets and high-speed maneuvering targets can be realized. Besides, the optical synthesis imaging unit and the laser emitting unit of each light beam emission and imaging sub-module share one sub-aperture, one light path unit and one light splitting unit, so that the overall weight and the size of the array light beam emission and imaging integrated device can be smaller.

Description

technical field

[0001] The present invention relates to the technical field of optical emission imaging, in particular to an array beam emission and imaging device, system and method of use. Background technique

[0002] Directed energy equipment is a device that uses a high-energy laser beam to irradiate a target. It has become a research hotspot at home and abroad for its precise light-speed strike, anti-electromagnetic, easy maintenance, and high combat efficiency and cost ratio.

[0003] In the related art, according to the working mode, directed energy equipment is divided into two systems: common aperture emission and array beam synthesis emission. Among them, the common aperture launch system can effectively improve the target power of the system by increasing the launch aperture, but as the aperture of the optical system increases, the volume weight of the system increases, and when the launch aperture is larger than the atmospheric coherence length, the beam is Atm...
