bend loss
The loss of optical power in an optical fiber because radiation escapes through its bends. The radiation loss caused by fiber bending is proportional to the bend radius.
electronic shutter
A mechanical shutter that has had its timing escapement replaced with an electronic timing circuit. This circuit allows a...
rotary laser
A structured light device using a rapidly rotating laser to project a beam of light that appears to the human eye as a...
Gires-Tournois interferometer
An interferometer similar in construction to a Fabry-Perot interferometer but having a rear mirror with high reflectivity,...
sky filter
A filter designed to decrease the luminosity of the sky without decreasing that of the landscape in the foreground. A filter...
helium-neon laser
A helium-neon (HeNe) laser is a type of gas laser that emits visible red light at a wavelength of 632.8 nm. It operates...
point cloud
A point cloud is a set of data points in a three-dimensional coordinate system, where each point represents a specific...
black hole
A cosmic phenomenon in which the mass and density of a star pass a critical point so that the escape velocity matches the...
spectral signature
A spectral signature, in the context of remote sensing and spectroscopy, refers to the unique pattern or characteristic...
Joule-Thomson cooler
A detector cooling device in which a gas under high pressure escapes through an expansion valve in the tank; as the escaped...
antiguide
A waveguide that has a core with a lower refractive index than the refractive index of the cladding. This structure can...
wide-angle lens
A wide-angle lens is a type of camera lens that has a shorter focal length than a standard or normal lens, allowing it to...
