Incoherent computer-generated holography
WebThe remaining chapters explore holographic interferometry, color holography, and computer-generated holograms. The final chapter deals with hologram replication, television transmission of holograms, and formation of holograms using spatially incoherent subject light. WebMay 22, 2024 · Incoherent digital holography is a technique to record the complex amplitude distribution of fluorescent, natural light, or another spatially incoherent light, and to reconstruct a 3D image of a scene using a computer [11–20]. Most incoherent digital holography systems adopt temporal phase-shifting interferometry.
