Ultra fast Fizeau interferometer “DELTAPH”

Ultra fast Fizeau interferometer “DELTAPH”

The state of the art interferometer “DELTAPH” sustained by our unique High speed polarization camera “CRYSTA”. The system can measure phase shift image from one snapshot fringe image without mechanical scanning. Its high-speed and real-time capabilities allow the evaluation of fast-moving dynamic phenomena.
