Dynamic laser interferometer
PhaseCam 4020HP
4D Technology
The PhaseCam 4020HP incorporates a single camera, high-speed optical phase sensor that makes a wavefront measurement in less than 30 microseconds--hundreds of times faster than a temporal phase shifting interferometer. Because acquisition time is so short, the PhaseCam can be used without vibration isolation or turbulence control, making it ideally suited for use on the production floor, in clean rooms and in environmental test chambers.
