Abstract

We present phase-shifting interferometry techniques applied for multidimensional incoherent digital holography and toward ultimately low light-intensity sensing. Using incoherent holography with multiwavelength-multiplexed phaseshifting interferometry that is termed computational coherent superposition (CCS), full-color three-dimensional (3D) information of an incoherent object can be obtained from the recorded wavelength-multiplexed self-interference holograms. Furthermore, an optical setup of incoherent holography based on CCS is implemented as a palm-sized incoherent digital holographic sensing system, termed “Holosensor.” Using incoherent holography with single-shot phase-shifting holography, high-speed 3D motion-picture imaging has been demonstrated. Phase-shifting interferometry is also a powerful 3D sensing technique for ultimately low light-intensity conditions.
