Optical computing or photonic computing uses light waves produced by lasers or incoherent sources for data processing, data storage or data communication for computing. For decades, photons have shown promise to enable a higher bandwidth than the electrons used in conventional computers (see optical … See more The fundamental building block of modern electronic computers is the transistor. To replace electronic components with optical ones, an equivalent optical transistor is required. This is achieved by crystal optics (using … See more A significant challenge to optical computing is that computation is a nonlinear process in which multiple signals must interact. Light, … See more Time delays optical computing The basic idea is to delay light (or any other signal) in order to perform useful computations. Of interest would be to solve NP-complete problems as those are difficult problems for the conventional computers.

Here I apply the theory to the problem of incoherent imaging under the effects of diffraction and photon shot noise, where the object may consist of an arbitrary number ... 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. northern mat and bridge grand prairie
