Glossary

wavefront In considering a field of electromagnetic energy emanating from a source, the wavefront is a surface connecting all field points that are equidistant from the source.
sensor 1. A generic term for detector. 2. A complete optical/mechanical/electronic system that contains some form of radiation detector.
Hartmann test A test for spherical aberration, coma or astigmatism in which incident rays from a point source are isolated by small holes in a metal disc located close to the lens or mirror under test. Photographic plates are inserted into the beam within and...
phase-modulated sensor A phase-modulated sensor is a type of sensor that uses modulation of the phase of a signal to measure changes in a physical quantity. In such sensors, variations in the phase of the signal are directly related to the changes in the parameter being...
Shack-Hartmann wavefront sensor The Shack-Hartmann wavefront sensor is an optical device used for measuring the wavefront aberrations of an optical system. It is widely used in adaptive optics systems to correct distortions and improve the quality of optical images in real-time....
