The design of holographic displays usually involves a trade-off between size and viewing angle. Here, the authors combine holographic projection with a digitally designed holographic optical element so that display size and the visual angle can be de

Light field 3D displays require a precise alignment between the display source and the micromirror-array screen for error free 3D visualization. Hence, calibrating the system using an external camera becomes necessary, before displaying any 3D conten

We propose a phase-shifting interferometry technique using only two in-line phase-shifted self-interference holograms. There is no requirement for additional recording or estimation in the measurement. The proposed technique adopts a mathematical mod

Phase-shifting interferometry selectively extracting wavelength information has been proposed since 2013, which is called computational coherent superposition (CCS) of multiple wavelengths. In this proceeding, we apply CCS to self-interference incohe

We can record digitally-designed information of three-dimensional (3D) objects or optical elements on a holographic photosensitive material by using wavefront printing technology. But the hologram data generated from the digitally-designed informatio

We present approaches for simultaneous, holographic, and microscopic multicolor motion-picture sensing of multiple natural light sources. We utilize single-shot incoherent digital holography with a polarization-imaging sensor, phase-shifting interfer
