脉冲响应函数与平面周期物体构成任意光学系统的成象特性研究——理论与实验

本文首先用线性系统中脉冲响应函数的概念分析了光学系统中平面周期物体的广义Talbot效应,利用我们以前导得的Talbot和Lau成象条件,导出了广义Talbot成象条件,得到十分简洁的系统脉冲响应表示式,然后利用光学系统的线性叠加和相关原理研究了任意光学系统中Talbot效应、Lau效应和多重成象现象及其相互关系,最后讨论了任意光学系统中三者之间的关系,并进行了实验证明。所用方法简单明了。

IMPULSE RESPONSE TRANSFER FUNCTION AND THE IMAGING PROPERTIES OF THE PLANE-PERIODIC OBJECT IN THE GENERAL OPTICAL SYSTEM——THEORY AND EXPERIMENT INVESTIGATION

In this paper, based on the Impulse response transer function the genear Talbot effect of the plan-periodic object in the general optical system is discussed, the amplitude distribution is derived using the Talbot imaging conditions deduced by us in the previous paper. Also based on the above analyses, the Talbot effect, Lau effect, multiple imaging and their relations are also discussed by using the linear superposition and correlation. Experiment results are also given, The method is simple.
