Precise Measurement for Manufacturing

PhaseCamT is a dynamic interferometer system that enables precise measurement of three-dimensional surfaces in the manufacturing industry. With this product, vibrations, moving parts, air turbulence, and other impediments are no longer a serious barrier to interferometric testing. Unlike phase-shifting interferometers, the system works by capturing data in a single frame, measuring data rates in tens of microseconds. By using a single camera to record four data frames at the exact same time, PhaseCam eliminates critical alignment issues and simplifies calibration, while enabling users to make interferometric measurements right on the factory floor. The system can be configured for many different applications, including mirror phasing, vacuum/cryogenic testing, motion/modal analysis, and flow visualization. Customers include leading aerospace and optical manufacturers such as Eastman Kodak Company, Ball Aerospace & Technologies Corporation, and the University of Arizona Mirror Laboratory. NASA uses the technology to test mirror technologies for next-generation space telescopes. PhaseCamT is a trademark of 4D Technology Corporation.
