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.
Optical heart-rate sensor. Electro-optical sensors are used whenever light needs to be converted to energy. Because of this, electro-optical sensors can be seen almost anywhere. Common applications are smartphones where sensors are used to adjust screen brightness, and smartwatches in which sensors are used to measure the wearer's heartbeat.
Electro Scientific Industries, Inc. (ESI) is an American high technology company headquartered in the Portland, Oregon, metropolitan area, specifically in Beaverton, Oregon, since 2021, but from 1963–2021, it was based in the unincorporated Cedar Mill area just north of Beaverton.
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.
SYERS 2 is an optical and infrared camera with a 40 cm aperture and a field of view larger than 2 degrees. It uses Time Delay and Integration CCD sensors to compensate for ground motion, resulting in a resolution of 1m (NIIRS 4) from a nominal 300 km orbit. [7] SYERS 2 is supplied by the Goodrich Corporation.
Optoelectronic devices are electrical-to-optical or optical-to-electrical transducers, or instruments that use such devices in their operation. [ 1 ] Electro-optics is often erroneously used as a synonym, but is a wider branch of physics that concerns all interactions between light and electric fields , whether or not they form part of an ...
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.
In 1995, he became the acting chief scientist for avionics, a position he held for 32 months. In 2001, he became senior scientist for electro-optical sensors and, in 2005, he became chief scientist for sensors, as part of the Air Force Research Laboratory. [2] McManamon is widely recognized as the Father of the Optical Phased Array technology.
