Abstract

We propose integrated phase-shifting digital holography using statistical approach. In the integrated phase-shifting scheme, the phase shifts are generated by a reference mirror moving with a uniform velocity, and sequential phaseshifted holograms are captured. Therefore, there is no wait time for stabilization, which offers some advantages such as short measurement time, high phase stability and high noise tolerance. The proposed method does not require precise control and calibration of the phase shifter and synchronization between the phase shifter and the digital image sensor. Therefore, the practical digital holography system with high accuracy can be implemented at low cost.
