提出了一种基于内积商的盲相移全息相移提取方法。该方法不需要物光波强,只需要获得任意相移值和参考光强度不等的三帧全息图。该算法能够准确地提取出两个相移值,消除了背景噪声和直流分量的影响。仿真和实验结果表明,相位步恢复的准确性和重建的目标波的复振幅的可行性。
This paper presents a phase-shift extraction method for blind phase-shifting holography applications based on the quotient of inner products. The method only requires acquiring three-frame holograms with arbitrary unequal phase-shift values and the intensity of the reference wave, without requiring the object wave intensity. Two phase shift values can be extracted precisely using the algorithm, which can remove the background noise and DC component effects. Both simulated and experimental results have demonstrated the phase step retrieval accuracy and the feasibility of reconstructing the complex amplitude of the object wave.
