Optical axis grating — Optical axis gratings (OAGs) are gratings of optical axis of a birefringent material. In OAGs, the birefringence of the material is constant, while the direction of optical axis is periodically modulated in a fixed direction. In this way they are … Wikipedia
Electromagnetically induced grating — (EIG) is a physics phenomenon based on light interference (or, more generally, on electromagnetic fields) where an interference pattern is used to build a dynamic spatial diffraction grating in matter. Introduction Electromagnetically induced… … Wikipedia

Fiber optic sensor — A fiber optic sensor is a sensor that uses optical fiber either as the sensing element ( intrinsic sensors ), or as a means of relaying signals from a remote sensor to the electronics that process the signals ( extrinsic sensors ). Fibers have… … Wikipedia
Optical vortex — An optical vortex (also known as a screw dislocation or phase singularity) is a zero of an optical field, a point of zero intensity. Research into the properties of vortices has thrived since a comprehensive paper by Nye and Berry, in 1974,[1]… … Wikipedia
