WebThe last digital hologram reviewed here is the Fresnel incoherent correlation hologram. In this motionless holographic technique, light is reflected from the 3-D scene, propagates through a diffractive optical element (DOE), and is recorded by a digital camera. Three holograms are recorded sequentially, each for a different phase factor of the DOE. WebMay 22, 2024 · The concept of the proposed digital holography is based on incoherent digital holography and parallel phase-shifting. Incoherent digital holography can be implemented with a single-path setup by using a spatial light modulator (SLM); this is called Fresnel incoherent correlation holography (FINCH) [14–17].An SLM generates two waves …

WebWhile the term incoherent holography refers to the method of forming holograms, the term digital holography refers to the recording of the holograms by a digital camera and to the digital reconstruction of holograms. Explicitly, digital holograms recorded by digital cameras are reconstructed in digital computers by digital algorithms. WebJul 16, 2024 · Digital holography [ 6, 7, 8] can also be classified as indirect imaging, although it is special in the sense that the pattern recorded by the image sensor is an interference pattern between two light beams. At least one of the beams originates from the object.

WebThis 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. Webments of incoherent holography techniques such as op-tical scanning holography [1] and Fresnel incoherent correlation holography (FINCH) [2,3]. The latter has fun-damental system robustness since it is based on a single channel incoherent interferometer and because it does not require any scanning or mechanical movement. How-
