Abstract

The range-gated imaging technique can effectively restrain the backscattering of light and greatly improve the observation distance of photoelectric imaging system in day and night with bad weather. In this paper, a miniature near-infrared laser range-gated imaging system is designed. It is convenient to operate and observe. The system uses four external function buttons to control gating distance, strobe width and clear imaging. FPGA serves as the main control chip to realize the synchronous control of the system. MicroBlaze inside the FPGA is used to configure codec chip for realizing the input/output of PAL video. An image enhancement method is transplanted to FPGA, which greatly enhances the imaging quality of the system and improves the detection distance. Compared to conventional imaging systems, the system improves the observation distance by 3-5 times.
