Abstract :
In high-speed 3D imaging by using parallel phase-shifting digital holography, there is a problem that the computational cost is very huge. Therefore, we have studied and developed special purpose computers for accelerating the calculation of parallel phase-shifting digital holography to solve the problem. However, the computational circuit for parallel phase-shifting interferometry and the special-purpose computer for light propagation have been independently designed. In this paper, we aim to connect them in order to realize high-precision and high-speed 3D imaging system by parallel phase-shifting digital holography.
