Request InfoFor Accurate Optical Phase Measurements4D Technology CorporationTUCSON, 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 vibration isolation equipment and enabling the capture and study of transient or dynamic events.
