Optical switch technology was introduced in 1962 by Harley E. Kelchner for use in a typewriter machine with the purpose of reducing the noise generated by typewriter keys. An optical keyboard technology utilizes light-emitting devices and photo sensors to optically detect actuated keys.
An optical transistor, also known as an optical switch or a light valve, is a device that switches or amplifies optical signals.Light occurring on an optical transistor's input changes the intensity of light emitted from the transistor's output while output power is supplied by an additional optical source.
One currently active field of research is the use of linear optics versus the use of nonlinear optics in quantum computing.For example, one model of linear optical quantum computing, the KLM model, is universal for quantum computing, and another model, the boson sampling-based model, is believed to be non-universal (for quantum computing) yet still seems to be able to solve some problems ...
The light travelling through the waveguides in an optical ring resonator remains within the waveguides due to the ray optics phenomenon known as total internal reflection (TIR). TIR is an optical phenomenon that occurs when a ray of light strikes the boundary of a medium and fails to refract through the boundary.
The slotted optical switch, sometimes known as opto switch or optical switch but not to be confused with the optical component, is a device comprising a photoemitter (e.g. LED) and a photodetector (e.g. photodiode) mounted in a single package so that the photoemitter normally illuminates the photodetector, but an opaque object can be inserted in a slot between them so as to break the beam.
This optical illusion dividing the internet tricks our brains into seeing the color red in a traffic light even though it's actually gray.
RCA jack, normally yellow (often accompanied with red and white for right and left audio channels respectively) S-Video (Separate Video). Carries standard definition video and does not carry audio on the same cable. Mini-DIN 4-pin Component. In popular use, it refers to a type of analog video information that is transmitted or stored as three ...
