Optical coherence tomogram of a fingertip. It is possible to observe the sweat glands, having "corkscrew appearance" Interferometric reflectometry of biological tissue, especially of the human eye using short-coherence-length light (also referred to as partially-coherent, low-coherence, or broadband, broad-spectrum, or white light) was investigated in parallel by multiple groups worldwide ...
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.
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.
