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.
WebApr 10, 2024 · Projecting high-quality three-dimensional (3D) scenes via computer-generated holography is a sought-after goal for virtual and augmented reality, human–computer interaction and interactive learning. WebJun 16, 2024 · In incoherent holography techniques such as Fresnel incoherent correlation holography (FINCH), the light from an object is split into two, each of which is modulated differently from one...
WebIn this study, a postprocessing approach is developed, where synthetic PSFs capable of introducing special beam characteristics when processed with the object intensity are generated using an iterative algorithm. The method is applied to generate edge-enhanced images in both CAI as well as Fresnel incoherent correlation holography methods. WebFresnel-type diffractive optical elements (DOEs) for general beam shaping of monochromatic, spatially incoherent light are demonstrated. Direct and indirect methods, i.e., adding a lens' phase to the designed Fraunhofer-type DOEs, are used for the design. The indirect method can reduce the calculation time by approximately half without loss of …
