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 stroboscopic microscopic interferometry based on Fourier transform method (FTM) is put forward to measure the out-of-plane motion of micro-resonator and micro-cantilever.
