Incoherent computer-generated holography
WebApr 4, 2024 · Computer-generated holograms are crucial for a wide range of applications such as 3D displays, information encryption, data storage, and opto-electronic computing. Orbital angular momentum (OAM), as a new degree of freedom with infinite orthogonal states, has been employed to expand the hologram bandwidth. However, in order to … 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.
