The PhaseCam™ 5030 from 4D Technology (Tucson, AZ) 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 utilizes Dynamic Interferometry® to acquire all measurement information in a single exposure, enabling measurement in the presence of vibration and air turbulence. Using a high-speed optical phase sensor that eliminates the need for slow, piezo-based phase-shifters, the PhaseCam 5030 can measure more than 10,000 times faster than a conventional phase-shifting interferometer. The turnkey PhaseCam system includes the interferometer, high-speed computer system, and extended-length cables for remote operation. 4Sight™ analysis software provides extensive 2D and 3D analysis options, as well as comprehensive data filtering, masking, database and import/export functions.
