What is Electro-optical targeting system?

Microstructured optical arrays are instruments for focusing x-rays. MOAs use total external reflection at grazing incidence from an array of small channels to bring x-rays to a common focus. This...

An optical train, also called an optical assembly, is an arrangement of optical components to guide a line of sight and/or a laser beam. For example, the position and angle...

An acousto-optical spectrometer is based on the diffraction of light by ultrasonic waves. A piezoelectric transducer, driven by the RF signal , generates an acoustic wave in a crystal. This...

In the field of photonics, optical chaos is chaos generated by laser instabilities using different schemes in semiconductor and fiber lasers. Optical chaos is observed in many non-linear optical systems....

Optical cross section is a value which describes the maximum amount of optical flux reflected back to the source. The standard unit of measurement is m/sr. OCS is dependent on...

Optical decay is process of relaxation of excitation of an excited quantum system, usually due to the spontaneous emission of a photon or a phonon.Optical decay is dominant mechanism of...

Optical lift is an optical analogue of aerodynamic lift, in which a cambered refractive object with differently shaped top and bottom surfaces experiences a stable transverse lift force when placed...

An optical parametric amplifier, abbreviated OPA, is a laser light source that emits light of variable wavelengths by an optical parametric amplification process. It is essentially the same as an...

A multivariate optical element , is the key part of a multivariate optical computer; an alternative to conventional spectrometry for the chemical analysis of materials. It is helpful to understand...

The controlled source electromagnetic method, also called sea bed logging, is a mostly offshore geophysical technique, employing electromagnetic remote-sensing technology to map the electric resistivity distribution of the subsurface. The...
