Developed by Kollmorgen in the 1990s, the Mark 46 Mod 0–1 OSS is a stabilized imaging sensor. It improves ships' situational awareness, aids in navigation, enables the crew to visually identify and track targets, and supplements the main combat sensors.
Electro–optics is a branch of electrical engineering, electronic engineering, materials science, and material physics involving components, electronic devices such as lasers, laser diodes, LEDs, waveguides, etc. which operate by the propagation and interaction of light with various tailored materials.
Electro-optic modulators are usually built with electro-optic crystals exhibiting the Pockels effect. The transmitted beam is phase modulated with the electric signal applied to the crystal. Amplitude modulators can be built by putting the electro-optic crystal between two linear polarizers or in one path of a Mach–Zehnder interferometer.
An optical sensor converts light rays into electronic signals. It measures the physical quantity of light and then translates it into a form readable by an instrument. An optical sensor is generally part of a larger system that integrates a source of light, a measuring device, and the optical sensor. This is often connected to an electrical ...
Pockels cells are also used in regenerative amplifiers, chirped pulse amplification, and cavity dumping to let optical power in and out of lasers and optical amplifiers. [10] Pockels cells can be used for quantum key distribution by polarizing photons. Pockels cells in conjunction with other EO elements can be combined to form electro-optic probes.
The Electro-Optical Systems Laboratory is one of eight labs in the Georgia Tech Research Institute and one of three labs under the Electronics, Optics, and Systems directorate. [1] It conducts basic and applied research into electro-optical topics and supports electro-optical education at the university level.
Microoptoelectromechanical systems (MOEMS), also known as optical MEMS, are integrations of mechanical, optical, and electrical systems that involve sensing or manipulating optical signals at a very small size. MOEMS includes a wide variety of devices, for example optical switch, optical cross-connect, tunable VCSEL, microbolometers.
Electro-optical MASINT also generates information on phenomena that emit, absorb, or reflect electromagnetic energy in the infrared, visible light, or ultraviolet spectra, phenomena where a "picture" is less important than the amount or type of energy reported. For example, a class of satellites, originally intended to give early warning of ...
