Incoherent holography
Webas stars and planets, are incoherent sources. A number of techniques have been put forward for holography of incoherent sources since the early years of conventional holography, including the grat-ing achromatic interferometer [20], the triangular interferometer [21], and conoscopic holography [22]. Experimental demonstrations of most of these ...

WebDec 28, 2024 · Incoherent holography is a hybrid imaging technology with coherent and incoherent processes. Compared with coherent holography, incoherent holography can alleviate coherent noise and speckle noise, and thus achieve higher signal-to-noise ratio. In this article, the incoherent holographic camera based on Michelson interferometer is … 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-
WebFINCH, an example of incoherent holography, is shown to simplify the process, eliminating many steps in metrology and at the same time increasing throughput, resolution and accuracy of the method. A proposed technique requires only a single image capture with a non-moving camera rather than the capture of multiple stacks of images requiring ...
