We propose a single-shot digital holography in which the complex amplitude distribution is obtained by spatial-carrier phase-shifting (SCPS) interferometry and the correction of the inherent phase-shift error occurred in this interferometry. The 0th order diffraction wave and the conjugate image are removed by phase-shifting interferometry and Fourier transform technique, respectively. The inherent error is corrected in the spatial frequency domain. The proposed technique does not require an iteration process to remove the unwanted images and has an advantage in the field of view in comparison to a conventional SCPS technique.
我们提出了一种单次数字全息术,其中通过空间载波相移(SCPS)干涉测量法获得复振幅分布,并校正该干涉测量中出现的固有相移误差。通过相移干涉测量法和傅里叶变换技术分别去除 0 级衍射波和共轭像。在空间频率域中校正固有误差。与传统的 SCPS 技术相比,该技术不需要迭代过程来去除不需要的图像,并且在视场方面具有优势。
