Self-interference incoherent digital holography

Considering the practical issues, issues related to resolution, phase-shifting, and contrast should be addressed to implement the viable SIDH system. Super resolution image reconstruction technique can be directly applied to SIDH to enhance the resolution of the system without any change of configuration. To deal with the phase-shifting issue, we present an arbitrary phase shift retrieval algorithm which can reduce the number of phase-shift and accept the blind phase-shift. The single-shot imaging is also possible by adopting the off-axis configuration of SIDH.

A single-shot incoherent holographic imaging technique that adopts self-interference incoherent digital holography (SIDH) with slight tilt of the plane mirror in the optical configuration.Experimentally, we verify that the hologram and 3D reconstruction can be implemented incoherently with the proposed single-shot off-axis SIDH.

Full-color, three-dimensional images of objects under incoherent illumination are obtained by a digital holography technique. Color holographic images of daylight-illuminated outdoor scenes and a halogen lamp-illuminated toy figure are obtained. From a recorded hologram, images can be calculated, or numerically focused, at any distances for viewing.

An adaptive optical system based on incoherent digital holography is described. Wavefront sensing and compensation can be achieved by numerical processing of digital holograms of incoherent objects and a guide star, thereby dispensing with the hardware components of conventional adaptive optics systems, such as lenslet arrays and deformable mirrors.
