In this paper, the phase continue scan is combined with the sinusoidal phasemodulation to determine the vibration amplitude of object by time average ESPI.
利用光学连续相位扫描和正弦相位调制相结合,提出一种ESPI时间平均测振的定量分析方法。

Moreover, the optical phasemodulation behavior model of micro deformable mirror arrays is established for the first time.
首次建立了微变形镜阵列的光相位调制系统级模型。
