Abstract
This work presents the working principle for digital holography with arbitrary phase-step reconstruction using multiple holograms. The arbitrary phase-step of the reference wave can be easily estimated with two different approaches -blind searching algorithm (Meng et al.) and the limited area algorithm (Hsieh et al.). Using these approximations, the magnitude-contrast images are reconstructed without dc term and twin-image blurring, but the phase-contrast images are filled with phase distortion. Computer simulations are carried out to verify the proposed approach and optical experiments are performed to validate it. The optical results and spatial resolutions using different estimation of the phase-step are presented and discussed herein.
