摘　　要：在分析微光夜视系统视距理论的基础上,论证了用脉冲红外激光阵列助视提高微光夜视系统视距的可行性。针对激光助视易于暴露的缺陷,提出了微光夜视伪随机瞬态激光增强技术。系统研究了伪随机编码理论,并硬件实现了瞬态激光伪随机编码调制及同步图像捕捉控制电路。建立了脉冲红外激光助视微光夜视系统,进行了多次室内、野外试验及试验结果观测评估,取得了较好效果。On the basis of analysis on the stadia equation of the low light level （LLL） night vision system, the possibility is demonstrated that using pulse infrared laser array can improve the stadia of the LLL night vision system. The pseudo random laser enhancement technique is put forward to handle the limitation that the laser assistant system is easy to be detected. The pseudo random coding theory is studied, the control circuits of pseudo random laser modulating and image capturing synchronously are designed. The pulse infrared laser assistant system is established, many experiments and some observation evaluation on the experiments have been carried out. Some good results are obtained.
