Request Info4D Technology CorporationTUCSON, Arix., Aug. 24, 2007 -- The PhaseCam 5030 is a high-performance, Twyman-Green interferometer developed specifically to measure meter-class optics for terrestrial and space-based telescopes. Unlike traditional phase-shifting interferometers, the PhaseCam uses dynamic interferometry to acquire all measurement information in a single exposure, enabling measurement in the presence of vibration and air turbulence. The system is remotely operated for permanent mounting in measurement towers, environmental testing chambers or other locations where access to an interferometer is difficult.
