time-average holography

Automatic real time laser holography non destructive testing system

自动实时激光全息无损检测系统

There are two main ways to measure the vibration using the method of time-average digital holography: the vibration measurement of intensity and phase, both of them are based on the reconstructed image and the reconstructed wave field.

用时间平均数字全息可以进行振动的测量，主要有两类方法：基于再现像的光强测振和再现光场的相位测振。
