Optical holography
WebDec 1, 2024 · 2. Basic concept of the metasurface optical holography. 2.1. Conventional optical holography. Optical holography, which involves the full recording both the amplitude and phase of a wavefront, is superior to the conventional photography process in which only the amplitude information of light is recorded. Optical holography is a technique which enables an optical wavefront to be recorded and later re-constructed. Holography is best known as a method of generating three-dimensional images but it also has a wide range of other applications. A hologram is made by superimposing a second wavefront (normally called the … See more To understand the process, it is helpful to understand interference and diffraction. Interference occurs when one or more wavefronts are superimposed. Diffraction occurs when a wavefront encounters an object. The process … See more Items required To make a hologram, the following are required: • a suitable object or set of objects • part of the laser beam to be … See more General form The complex amplitude of a monochromatic electromagnetic wave can be represented by See more When the hologram plate is illuminated by a laser beam identical to the reference beam which was used to record the hologram, an exact reconstruction of the original object wavefront is obtained. An imaging system (an eye or a camera) located in the … See more
