speckle shearing interferometry

基本解释

Both theory and experiments show that stroboscopic shearing speckle interferometry is obviously superior to time-average method.
理论和实验都表明频闪剪切散斑干涉照相法要优于时间平均剪切散斑干涉照相法。
A kind of enciroled-circular double wedge (E-CDW), in which shearing amount could be varied continually, is recommended for speckle shearing interferometry.
本文提出一种错位量连续可调的圆一环双光楔作为错位干涉元件进行激斑照相。
Speckle-Shearing Interferometry is a kind of method that directly measures surface full-field strain. It does not need to differentiate with respect to the measured displacement to obtain the strain.
散斑剪切干涉法是一种直接测量表面全场应变的方法，它取消了由测定位移而计算微分的要求。
