电子散斑视频锁相系统

Electronic speckle interferometry video phase locked system

电子散斑锁相系统目前已有多种方法，其目的就是消除被测物体的振动，空气的扰动给电子散斑干涉计量带来的误差。本文提出了一种利用视频信号直接对电子散斑的相位锁定系统——视频锁相系统。

There are many phase locked mthods of ESPI,The purpose is to eliminate the error of measurement caused by vibration of objects and disturbance of air.This paper proposed an Video phase lock method.It can eliminate the influence caused by vibration of objects and disturbance of air effectively.
