Abstract

We propose the reconstruction algorithm for two-step parallel phase-shifting digital holography. Parallel phase-shifting digital holography records a single hologram and numerically extracts the multiple images needed for obtaining the complex amplitude in phase-shifting technique. During the reconstruction process, phase error and degradation of image occur due to the calculation error. The proposed algorithm interpolates into two steps that include the subpixel data to reduce the error, so the quality that a reconstructed image can be enhanced. Both numerical simulation and experiment are conducted to verify the effectiveness of the proposed algorithm.
