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 ...
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.
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.
Manufactured by Lockheed in Sunnyvale, California, the KH-11 was the first American spy satellite to use electro-optical digital imaging, and so offer real-time optical observations. [ 7 ] Later KH-11 satellites have been referred to by outside observers as KH-11B or KH-12, and by the names "Advanced KENNEN", "Improved Crystal" and "Ikon".
The electro-optic Pockels effect in nonlinear crystals (e.g. KDP, BSO, K*DP) can be used for electric field sensing via polarisation state modulation techniques. In this scenario, an unknown electric field results in polarisation rotation of a laser beam propagating through the electro-optic crystal; through inclusion of polarisers to modulate ...
A micrograph of the corner of the photosensor array of a webcam digital camera Image sensor (upper left) on the motherboard of a Nikon Coolpix L2 6 MP. The two main types of digital image sensors are the charge-coupled device (CCD) and the active-pixel sensor (CMOS sensor), fabricated in complementary MOS (CMOS) or N-type MOS (NMOS or Live MOS) technologies.
The New York Jets have once again been eliminated from the NFL playoff picture, pushing their league-worst drought to 14 seasons.
MEOSS (Monocular Electro-Optical Stereo Scanner), built by the German Aerospace Center (DLR), is an experimental sensor with pushbroom Charge-coupled device (CCD) technology. MEOSS is a stereo camera system capable of recording three images simultaneously with a single lens by means of linear scanning (3-line stereo system).
