PhaseCam 4000 Interferometer System
Jul 6, 2004 — TUCSON, Ariz., Jan. 26 -- The ultrahigh-speed PhaseCam 4000 interferometer system from 4D Technology Corp. of Tucson, Ariz., captures high-accuracy, quantitative optical phase measurements. It uses a computer-generated holographic diffraction grating and a polarization phase mask to simultaneously create four phase-shifted interferograms on a single, high-resolution detector array. The system can acquire data 10,000 times faster than conventional systems, eliminating the need for bulky...
