摘　　要：距离选通技术是激光主动照明成像系统中的关键技术;以TI公司DSP芯片TMS320F2812作为主控制芯片,设计了一种基于DSP的激光距离选通成像系统的同步控制器;给出了该控制器的功能和硬件结构以及软件流程设计;通过观测3km处的车牌目标对比试验,在非距离选通情况下,模糊不清;而在距离选通情况下,车牌目标细节清晰可见;实验结果表明,该控制器具有结构简单、延迟时间精确、实时性好等特点,可以满足激光主动照明成像系统的要求。Synchronism control technology is the crucial technology in range-gated laser active illuminated imaging system.Regards TIs DSP chip TMS320F2812 as the main chip,a kind of LRG imaging system based on the DSP is designed.The function and hardware structon of the controller,and software flow design has been given.By observing the contrastive experimentation of the car brand in 3 km,it gives the conclusion that in the non range-gating condition,the vague objective is seen,but the clear one is observed in the range-gating condition.The practice proved that the controller has advantages： simple structure,delay time precision,real time.The controller satisfied perfectly the laser active illuminated imaging system.
