Abstract

This work discusses a novel approach for numerical wavefront reconstruction, which utilizes arbitrary phase step digital holography. The experimental results reveal that only two digital holograms and a simple estimation procedure are required for twin-image suppression, and for numerical reconstruction. One advantage of this approach is its simplicity. Only one estimate equation needs to be applied. Additionally, the optical system can be constructed from inexpensive, generally available elements. Another advantage is the effectiveness of the approach. The tolerance of the estimated value is less than 1% of the actual value, such that the quality of the reconstructed image is excellent. This novel approach should facilitate the application of digital holography and promote its use.
