synthetic holography
1Synthetic 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 …
2Computer-generated holography — (CGH) is the method of digitally generating holographic interference patterns. A holographic image can be generated e.g. by digitally computing a holographic interference pattern and printing it onto a mask or film for subsequent illumination by… …

4Mathematics and Physical Sciences — ▪ 2003 Introduction Mathematics Mathematics in 2002 was marked by two discoveries in number theory. The first may have practical implications; the second satisfied a 150 year old curiosity. Computer scientist Manindra Agrawal of the… …
5Light field — The light field is a function that describes the amount of light traveling in every direction through every point in space. Michael Faraday was the first to propose (in an 1846 lecture entitled Thoughts on Ray Vibrations ) that light should be… …
6laser — /lay zeuhr/, n. Physics. a device that produces a nearly parallel, nearly monochromatic, and coherent beam of light by exciting atoms to a higher energy level and causing them to radiate their energy in phase. Also called optical maser. [1955 60; …
7Emmett Leith — Emmett N. Leith (* 12. März 1927 in Detroit; † 23. Dezember 2005 in Ann Arbor) war ein US amerikanischer Physiker und Pionier der Holografie. Leith studierte Physik an der Wayne State University (Bachelor Abschluss 1949, Master Abschluss 1952).… …
8History of radar — The history of radar starts with experiments by Heinrich Hertz in the late 19th century that showed that radio waves were reflected by metallic objects. This possibility was suggested in James Clerk Maxwell s seminal work on electromagnetism.… …
9Interferometric microscopy — or Imaging interferometric microscopy is the concept of microscopy whichis related to holography, synthetic aperture imaging, and off axis dark field illumination techniques.Interferometric microscopy allows enhancement of resolution of optical… …
