A multiple-beam interferometer, usually consisting of two flat plates, with high reflective ability. The plates are set parallel to one another by spacers so that lightwaves may bounce back and forth between them several times. The requirements for...

The altering of lightwaves by acoustic waves in a solid medium.

A technology that uses electrically activated holograms stored within specially developed crystals to route information in...

The phenomenon that makes nonlinear the mathematical expression for the electrical polarization of a medium through which...

The diffraction of a particle by a standing lightwave.

In a birefringent material, the index of refraction varies with the direction of vibration of a lightwave. That direction...

With respect to the effect of crystals on lightwaves, the family of curves having constant direction of polarization.

The individual coherent series of lightwaves that defines a quantum of radiant energy. Light quantum is equal to hv, h being...

The electric field associated with an electromagnetic wave and thus with a lightwave. The electric vector specifies the...

Trade name referring to an instrument that determines surface distances by measuring the length of time it takes for a...

The study of the physics of x-rays, where the x-rays exhibit properties similar to those of lightwaves. Also called Roentgen...

The use of an electric field or signal to couple a lightwave from one dielectric waveguide into another dielectric waveguide.

An instrument that employs the interference of lightwaves to measure the accuracy of optical surfaces; it can measure a...
