一种基于光纤阵列的激光照明方法

An uniform illumination system based on Laser 3D imaging is designed and the validity of the system is proved by taking simulation experiments. 64 paths of laser beam with average energy are emitted after the narrow infrared laser pulse emitted by fiber laser device passing through the fiber splitter. The exit array is placed around the focus spot of the optical system to produce dot-array lightening. The laser beam is reflected by target incidents on the receiving system, and then images in APD detector array, where each detection pixel corresponds to each point light source. The system designed can uniformize the light distribution and enhance the utilization efficiency of the laser light.
