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 type of sensor used in interferometers to compare the phase of light detected by a sensing fiber with that of a reference fiber. The two single-mode fibers are illuminated by the same coherent laser and are in phase; changes in the environment of...
