Incoherent digital holography
WebWe present a lensless, interferenceless incoherent digital holography technique based on the principle of coded aperture correlation holography. The acquired digital hologram by this technique contains a three-dimensional image of some observed scene. Light diffracted by a point object (pinhole) is modulated using a random-like coded phase mask ... http://faculty.cas.usf.edu/mkkim/papers.pdf/2012%20MKK%20AppOpt.pdf

WebAug 11, 2024 · Incoherent digital holography (IDH) is a technique of generating holograms using incoherent light such as natural light, light-emitting diode light, and fluorescence.
WebJun 16, 2024 · Incoherent digital holography (IDH) requires no spatial coherence; however, it requires high temporal coherence for a light source to capture holograms with high spatial resolution. Temporal coherence is often enhanced with a bandpass filter, reducing the light utilization efficiency.

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. cannabis in cancer treatmentWebSep 14, 2024 · One such well-established incoherent digital holography system called Fresnel incoherent correlation holography (FINCH) 14 makes use of the digital signal processing and self-referencing... cannabis in buchanan miWebments of incoherent holography techniques such as op-tical scanning holography [1] and Fresnel incoherent correlation holography (FINCH) [2,3].
