Abstract. Digital holography is an emerging field of new paradigm in general imaging applications. We present a review of a subset of the research and development activities in digital holography, with emphasis on microscopy techniques and applications. First, the basic results from the general theory of holography, based on the scalar diffraction theory, are summarized, and a general description of the digital holographic microscopy process is given, including quantitative phase microscopy. Several numerical diffraction methods are described and compared, and a number of representative configurations used in digital holography are described, including off-axis Fresnel, Fourier, image plane, in-line, Gabor, and phase-shifting digital holographies. Then we survey numerical techniques that give rise to unique capabilities of digital holography, including suppression of dc and twin image terms, pixel resolution control, optical phase unwrapping, aberration compensation, and others. A survey is also given of representative application areas, including biomedical microscopy, particle field holography, micrometrology, and holographic tomography, as well as some of the special techniques, such as holography of total internal reflection, optical scanning holography, digital interference holography, and heterodyne holography. The review is intended for students and new researchers interested in developing new techniques and exploring new applications of digital holography.

“…Techniques to overcome the diffraction limit have been suggested and studied by many researchers. [54][55][56][57][58][59][60][61] Synthetic aperture (SA) imaging is a well-researched approach to improve the resolving capabilities of an imaging system. In SA imaging, for a set distance between the observed target and the imager, the effective aperture of a system is synthetically extended, leading to an increased NA.…”

“…This pattern can be considered as being acquired by a virtual imager of an effective aperture that is wider than the actual physical aperture, and thus of a higher NA. [56][57][58][59][60][61] In this sense, SA is considered as a super-resolution method, since it increases the resolving power beyond the resolution limit of a single-finite aperture of the physical system. It is not surprising that techniques of holographic imaging are frequently used for implementing SA.…”

Abstract. Today, spatial light modulators (SLMs) offer the world of digital holography a robust technology that can be incorporated into hologram recorders. This review surveys recent developments related to the role of SLMs in a family of incoherent digital hologram recorders termed Fresnel incoherent correlation holography (FINCH). Two systems branching out from FINCH, and discussed herein, are a confocal version of FINCH and a synthetic aperture FINCH-based system.

“…The use of optical holography for synthetic aperture is usually restricted to coherent imaging [21][22][23] . Therefore, the use of this technique is limited only to those applications in which the observed targets can be illuminated by a laser.…”

Holographic imaging offers a reliable and fast method to capture the complete 3-D information of the scene from a single perspective. We review our recently proposed single-channel optical system for generating digital Fresnel holograms of 3-D real-existing objects illuminated by incoherent light. In this motionless holographic technique, light is reflected, or emitted, from a 3-D object, propagates through a spatial light modulator (SLM), and is recorded by a digital camera. The SLM is used as a beam-splitter of the single-channel incoherent interferometer, such that each spherical beam originated from each object point is split into two spherical beams with two different curve radiuses. Incoherent sum of the entire interferences between all the couples of spherical beams creates the Fresnel hologram of the observed 3-D object. When this hologram is reconstructed in the computer, the 3D properties of the object are revealed.
