We propose an algorithm that can improve the quality of the reconstructed image from the single hologram recorded by the optical system of the parallel four-step phase-shifting digital holography. The proposed algorithm applies the image-reconstruction algorithm of parallel two-step phase-shifting digital holography to the hologram so as to reduce errors in the reconstructed image and eliminate ghosts. We numerically and experimentally confirmed that the proposed algorithm decreased 25% in terms of root mean square error in amplitude, and eliminated the ghosts, respectively.
我们提出了一种算法，该算法可以提高由平行四步相移数字全息术的光学系统记录的单个全息图所重建图像的质量。所提出的算法将平行两步相移数字全息术的图像重建算法应用于全息图，以减少重建图像中的误差并消除重影。我们通过数值和实验证实，所提出的算法在幅度均方根误差方面降低了25%，并分别消除了重影。
