Abstract

A design scheme of laser protection system based on digital micro-mirror device (DMD) was proposed to reduce the damage of intense laser to optoelectronic imaging equipment. The working principle of the system

the model selection of DMD and CCD

the projection optical path and the design of optical conversion system were introduced in detail. The image pixels were tuned by using the phase-shifting Mohr method. The simulation results show that the system can successfully identify pixel coordinates and radiuses of the laser spot center points in different spot radiuses and light intensities

and achieve micro-mirror control of the corresponding regions of spots. The laser light intensity can be attenuated by over 70%.
