Abstract :
A virtual interferogram-generation algorithm is proposed to improve the performance of phase-shifting digital holography. Combining the intensity distribution of a signal and that of a reference beam with two observed interferograms, this algorithm generates four interferograms with different phases. Simulation results confirmed the basic operation of this algorithm.
