摘要
文中针对在浓密介质中进行激光探测时,所遇到的介质后向散射致使探测器饱和及疲劳接收问题,提出了一种基于光开关的新型激光探测技术,可以去除介质中强后向散射,解决探测器饱和及持续疲劳接收问题,从而实现浓密介质激光目标探测的高灵敏度,为达到更远探测距离提供了新的技术手段。
A newly high sensitivity laser detecting technology based on optic-switch technique is presented, to resolve the problems of detector absorption saturation and fatigue caused by backward dispersion on the condition of thickener medium laser detection. By application of this technology, backward dispersion can be reduced and the saturation and fatigue absorption problem is resolved, thus high sensitivity was achieved, and under water and remote laser detection ability is improved.
