  3. Natron (software) - Wikipedia

    en.wikipedia.org/wiki/Natron_(software)

    Natron is a free and open-source node-based compositing application. It has been influenced by digital compositing software such as Avid Media Illusion, Apple Shake, Blackmagic Fusion, Autodesk Flame and Nuke, from which its user interface and many of its concepts are derived. Natron supports plugins following the OpenFX 1.4 API.

    en.wikipedia.org/wiki/Microoptoelectromechanical...

    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.

  6. Slotted optical switch - Wikipedia

    en.wikipedia.org/wiki/Slotted_optical_switch

    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.

    en.wikipedia.org/wiki/Keyboard_technology

    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.

  9. Optical transistor - Wikipedia

    en.wikipedia.org/wiki/Optical_transistor

    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.
