The term laser is an acronym for ' Light Amplification by Stimulated Emission of Radiation '. [95] Laser light is usually spatially coherent , which means that the light either is emitted in a narrow, low-divergence beam , or can be converted into one with the help of optical components such as lenses.
An OTDR. An optical time-domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber.It is the optical equivalent of an electronic time domain reflectometer which measures the impedance of the cable or transmission line under test.
Lists of acronyms contain acronyms, a type of abbreviation formed from the initial components of the words of a longer name or phrase. They are organized alphabetically and by field. They are organized alphabetically and by field.
Usual meaning is the reciprocal of the distance between two just-distinguishable subject details. [7] S or TV: Shutter priority or time value. Automatic exposure mode where the photographer sets a shutter speed, and the AE firmware automatically sets the appropriate lens aperture. [4] SC: Soft Capture. Capture of light emitting objects as the ...
The back-formed verb "to lase" is frequently used in the field, meaning "to give off coherent light," especially about the gain medium of a laser; [16] when a laser is operating, it is said to be "lasing". [17] The terms laser and maser are also used for naturally occurring coherent emissions, as in astrophysical maser and atom laser. [18] [19]
Optics is the science of light and its interaction with matter.. Optics is a broad subject area. Much of the content is covered in subcategories. Many basic concepts are covered in Category:Geometrical optics, in which light is considered as if it were composed of rays.
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.
