March 16, 2005, Tucson, AZ--4D Technology has introduced a high performance, dynamic Twyman-Green interferometer system (PhaseCam 4010) with twice the spatial sampling of the original PhaseCam. Unlike phase-shifting interferometers, the PhaseCam works by acquiring all of the information to compute phase in a single exposure and is vibration insensitive.
The PhaseCam 4010 includes a single camera and a high-speed optical phase sensor that eliminates the need for phase shifters and has the ability to acquire data in as little as 1 msec. The new system has all of the features and benefits of the original PhaseCam, such as enabling precision measurements without the need of an isolation table, a standard Camera Link interface and a single-mode HeNe laser.
The PhaseCam 4010's insensitivity to vibration and air turbulence suit it for applications such as production floor quality control, optical metrology of large optical elements, astronomical optics and aerospace systems, clean room applications typically hampered by air flow turbulence, applications in vacuum and environmental chambers, and precise metrology on automated manufacturing machines such as polishers and diamond turning machines.
