aperture effect
1Aperture — For other uses, see Aperture (disambiguation). f stops demonstrated on a lens …
2Interferometric synthetic aperture radar — Interferometric synthetic aperture radar, also abbreviated InSAR or IfSAR, is a radar technique used in geodesy and remote sensing. This geodetic method uses two or more synthetic aperture radar (SAR) images to generate maps of surface… …
3Synthetic aperture radar — (SAR) is a form of radar in which the highly directional (and thus very large) rotating antenna used by conventional radar is replaced with many low directivity small stationary antenna positions scattered over some area near or around the target …
4Inverse synthetic aperture radar — (ISAR) is a technique to generate a two dimensional high resolution image of a target.In situations where other radars display only a single unidentifiable bright moving pixel, the ISAR image is often adequate to discriminate between various… …
5Coriolis effect — For the psychophysical perception effect, see Coriolis effect (perception). Classical mechanics Newton s Second Law …
6Red-eye effect — The red eye effect in photography is the common appearance of red pupils in color photographs of eyes. It occurs when using a photographic flash very close to the camera lens (as with most compact cameras), in ambient low light. Red eye effect… …
7Bloom (shader effect) — Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in computer games, demos and high dynamic range rendering (HDR) to reproduce an imaging artifact of real world cameras. The effect produces fringes (or… …
8Pockels effect — The Pockels effect, or Pockels electro optic effect, produces birefringence in an optical medium induced by a constant or varying electric field. It is distinguished from the Kerr effect by the fact that the birefringence is proportional to the… …
9Very small aperture terminal — A Very Small Aperture Terminal (VSAT), is a two way satellite ground station with a dish antenna that is smaller than 3 meters (most VSAT antennas range from 75 cm to 1.2 m). VSAT data rates typically range from narrowband up to 4 Mbit/s. VSATs… …
10Joule-Thomson effect — /joohl tom seuhn, jowl /, Thermodynam. the change of temperature that a gas exhibits during a throttling process, shown by passing the gas through a small aperture or porous plug into a region of low pressure. Cf. free expansion. [1895 1900;… …
