摘要
针对光电探测时仅用强度来处理信息的局限性, 通过理论分析, 提出一种利用脉冲激光反射、散射偏振态时间、空间相关检测的方法, 可以克服由于强度差过小带来的目标检测上的困难.利用分析结论, 通过计算偏振分布密度函数(Stokes矢量的概率密度函数), 进一步讨论了偏振传递函数的特性, 用于识别目标, 并给出了计算实例.
Abstract
A novel method to calculate temporal and spatial correlation by using the state of polarized pulse laser is presented,which can overcome the deficiency of the way only using amplitude of light in detecting target.More work can be done to deal with the polar state transfer function in order to identify target according to the consequent,computation examples are given.王海晏|whh_shx@yahoo.com.cn
