Speckle Interferemetry with Multiplexing Holograph Recording
-
摘要: 在普通双曝光散斑干涉计量中,引入多通道全息记录,可以在一张负片上得到连续变化的物体在不同时间间隔内各种状态之间两两相对面内位移的情况。此种记录装置简单,操作方便,是一种可行的多通道散斑干涉计量的新方法。Abstract: A technique for speckle interferometry with multiplexing holohraph recording is presented. With this method, states and events of object at discrete time intervals can be recorded and studied on the same time using a multislit diaphragm. The experimental results are given.
