WebJul 16, 2024 · Coded aperture correlation holography (COACH) combines incoherent digital holography with coded aperture imaging. COACH is also a method to record incoherent digital holograms of three-dimensional object scenes. Still, COACH can be used for several other incoherent and coherent optical applications. In this chapter, we survey the prime … WebFeb 1, 2024 · Incoherent digital holography (IDH) is an optical technique of 3D imaging with a single sensor. 3D information of a light wave is recorded using light interference. A hologram is digitally recorded even for a spatially incoherent light wave. The 3D image of a light wave is reconstructed from the recorded hologram using a computer.
Webputerized holography.Theworldof computerized holograms is roughly divided into two main types of holograms: com-puter-generated holograms (CGHs) 1 and digital holograms (DHs). 2 In general, SLMs are used as an interface between the electronic and optical domains and are, therefore, highly important for these two types of holograms. Usually, a CGH WebThis roadmap article focuses on spatially incoherent digital holography (IDH). Representative IDH methods such as optical scanning holography (OSH), Fresnel incoherent correlation holography (FINCH), coded aperture correlation holography (COACH), IDH with a Fresnel zone aperture, and IDH with an interferometer along with a state-of-the-art optical …
WebHolographic imaging may become severely degraded by a mixture of speckle and incoherent additive noise. Bayesian approaches reduce the incoherent noise, but prior information is needed on the noise statistics. With no prior knowledge, one-shot reduction of noise is a highly desirable goal, as the recording process is simplified and made faster.
