摘　　要：为了有效提升光电成像系统焦平面探测器在外界存在激光干扰条件下的环境适应性,同时不显著降低原成像系统成像性能,提出了一种基于编码成像的激光能量调控方法,构建了一套以液晶空间光调制器为核心器件的编码成像实验系统并对该系统的成像性能进行了测试,设计了一套基于编码成像的激光能量调控实验验证系统并开展了多参数条件下编码成像抗激光干扰实验研究。实验结果表明,基于编码成像的激光能量调控方法可在不显著降低成像质量前提下有效提升焦平面探测器的抗激光干扰性能。A laser energy modulation method based on the coding imaging system was proposed,which allowed the focal plane detector to improve its environmental adaptability with the existence of laser jamming and keep its imaging quality with small fraction loss.A coding imaging system based on the liquid crystal spatial light modulator was constructed and its imaging performance was tested.A laser energy modulation experimental validation system was designed and experiment on the capacity of resisting laser jamming by using coding imaging method under multiple parameters was conducted.The experiment results indicated that the proposed laser energy modulation method based on the coding imaging system can improve the capacity of resisting laser jamming of focal plane detector effectively without significant loss of imaging quality.
