Abstract

The paper introduces an optoelectronic/image processing module, OIMP, which enables more convenient implementation of full-field optical methods of testing into industry. OIMP consist of two miniature CCD cameras and optical wavefront modification system which recombines the beams produced by opto-mechanical measurement system and images fringe patterns on the CCD matrices. The modules makes possible simultaneous registration of there monochromatic images as R,G,B components of color video signal by means of signal frame grabber or by VCR on video tape. This enables convenient and inexpensive storage of large quantities of data which may be analyzed by spatial carrier phase shifting method of automatic fringe pattern analysis. THe usefulness of OIMP is shown by two examples: u and v in-plane displacement simultaneous analysis in grating interferometry system and complex shape determination by fringe projection systems.
