Manufactured by 4D Technology Corp., the PhaseCam 4010 is a dynamic Twyman-Green interferometer system with twice the spatial sampling of its predecessor. In a single exposure, it acquires all of the information needed to compute phase, and it acquires data in 1 µs. The turnkey system comprises a single camera, a high-speed optical phase sensor, a Camera Link interface and a single-mode HeNe laser that eliminates mode hopping, and it allows short exposure and long life. It is insensitive to vibration and air turbulence. A Pentium IV computer and 4Sight software are included.
