WebThe method is applied to generate edge-enhanced images in both CAI as well as Fresnel incoherent correlation holography methods. Coded aperture imaging (CAI) methods offer … WebIncoherent Holography Incoherent holography combines the holographic principle to retrieve amplitude and phase information via interferometric means with shearing interferometry. Incoherent holography Shearing interferometry is well suited for short/partially coherent light sources.

Fresnel incoherent correlation holography with single camera shot

WebMar 4, 2024 · However, incoherent digital holography 2,3 eliminates the coherence requirement; instead, it is based on a passive recording process and can form holograms … WebJul 25, 2024 · An incoherent digital holographic imaging system based on the Michelson interferometer with structured light illumination is proposed, which uses a spatial light modulator (SLM) to realize horizontal and vertical cosine grating illumination patterns to improve the lateral resolution of the imaging system.

Double-sided computer-generated 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 ... WebJul 26, 2024 · The spatial incoherence removes speckle noise in CGH, and the temporal incoherence simplifies the optical setup, including the light source. We demonstrate two- … WebWe present a new method for recording digital holograms under incoherent illumination. Light is reflected from a 3D object, 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. csr polyester insulation
