Speckle interferometry is a sophisticated technique for the non-contact, high precision measurement of form, deformation and vibration of technical surfaces. In this paper, a new single frame phase-shifting speckle interferometer for the quantitative measurement of out-of-plane-deformations is described and first measurements are presented. With a binary phase grating, six interference patterns are generated at a time. They are acquired within one frame time of a single CCD- camera, thus minimizing errors due to thermal fluctuations or vibrations. The use of fiber optics allows a flexible application of the system under industrial conditions and a compact design of the sensor head.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.
