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 trigger. The trigger reacts to a change in the signal within the light sensor. An optical sensor can measure the changes from one or several light beams.
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.
These will be nonlinear optical crystals used to manipulate light beams into controlling other light beams. Like any computing system, an optical computing system needs four things to function well: optical processor; optical data transfer, e.g. fiber-optic cable; optical storage, [8] optical power source (light source)
Electronic light sensors. Optoelectronics (or optronics) is the study and application of electronic devices and systems that find, detect and control light, usually considered a sub-field of photonics. In this context, light often includes invisible forms of radiation such as gamma rays, X-rays, ultraviolet and infrared, in addition to visible ...
CCD sensors are used for high end broadcast quality video cameras, and CMOS sensors dominate in still photography and consumer goods where overall cost is a major concern. Both types of sensor accomplish the same task of capturing light and converting it into electrical signals. Each cell of a CCD image sensor is an analog device.
On the left, the main IR sensor (100 km range), on the right a TV/IR identification sensor with laser rangefinder (40 km range) An electro-optical targeting system (EOTS), is a system employed to track and locate targets in aerial warfare. [1] It can use charge-coupled device TV cameras, laser rangefinders and laser designators.
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.
The electro-optical transfer function (EOTF) is the transfer function having the picture or video signal as input and converting it into the linear light output of the display. [1] This is done within a display device. The opto-optical transfer function (OOTF) is the transfer function having the scene light as input and the displayed light as ...
