Multi-target multi-attitude parallel tracking system and method based on liquid crystal spatial light modulator

Abstract

The invention discloses a multi-target multi-pose parallel tracking system and method based on a liquid crystal spatial light modulator. The system comprises a coherent light source, a beam expander, a first reflection mirror, a shutter, a second reflection mirror, the spatial light modulator, a first convex lens, a beam splitter, a CCD camera, a third reflection mirror, a second convex lens, a camera, a working plane and a computer. According to the multi-target multi-pose parallel tracking system and method based on the liquid crystal spatial light modulator, real-time images of all targets are transmitted to the control computer through the camera, click operation is preformed through an infrared touch screen, Labview calculation is adopted, a GS algorithm is used, a hologram is worked out, then the hologram is loaded into the liquid crystal SLM, multiple light beams are generated, and the targets are hit flexibly. According to the multi-target multi-pose parallel tracking system and method, the liquid crystal SLM is convenient to operate and flexible to use; automatic light emitting and hitting are performed through Labview control, no manual light beam adjustment is needed, the number and positions of the light beams can be controlled flexibly, and the time is saved; and by the adoption of the spatial light modulator (SLM), the light beams can be generated, all the targets are hit at the same time, and the energy utilization rate of a laser is increased.

Description

technical field [0001] The invention belongs to the technical field of laser and control, and specifically relates to an optical system that uses an SLM (liquid crystal spatial light modulator) to generate multiple beams, controls it with Labview, and strikes a target. Background technique [0002] The invention of the laser is a major scientific and technological achievement that can be compared with atomic energy, semiconductors, and computers in the 20th century. It has developed rapidly since its birth, and the appearance of laser light source is another revolution in the history of artificially manufactured light sources. Since the first ruby ​​laser was introduced in 1960, the study of laser-material interaction has been carried out. After more than 40 years of development, in order to meet different needs, various lasers have emerged and are widely used in industrial processing and medical fields. The laser wavelength covers almost infrared to extreme ultraviolet ba...
