Optical theorem — In physics, the optical theorem is a general law of wave scattering theory, which relates the forward scattering amplitude to the total cross section of the scatterer. It is usually written in the form where f(0) is the scattering amplitude with… … Wikipedia
Optical cavity — An optical cavity or optical resonator is an arrangement of mirrors that forms a standing wave cavity resonator for light waves. Optical cavities are a major component of lasers, surrounding the gain medium and providing feedback of the laser… … Wikipedia
Optical depth — For other uses, see Optical depth (astrophysics). Optical depth, or optical thickness, is a measure of transparency. Optical depth is defined by the negative logarithm of the fraction of radiation (e.g., light) that is not scattered or absorbed… … Wikipedia
