我们提出了并行准相移数字全息作为一种技术，能够无噪声的三维物体的瞬时测量。该技术使用位于参考光束中的相移阵列器件一次实现四种相移。该装置是2x2相位延迟器的阵列。我们进行了数值模拟和初步的实验，结果与传统的相移方法吻合得很好。此外，其结果上级单独使用菲涅耳变换的结果，这是另一种可以实现瞬时测量的数字全息方法。(C)2004年，美国物理学会。
We propose parallel quasi-phase-shifting digital holography as a technique capable of noiseless instantaneous measurement of three-dimensional objects. The technique implements four kinds of phase shifting at a time using a phase shifting array device located in the reference beam. The device is an array of 2x2 phase retarders. We conduct both numerical simulation and preliminary experiment, and the results agree well with those of the conventional phase shifting method. Also, the results are superior to those using a Fresnel transform alone, which is another digital holography method that can achieve instantaneous measurement. (C) 2004 American Institute of Physics.
