Abstract
An opto-electronic system for the evaluation of double-exposure and double-pulse holographic interferograms is presented. Video-electronic detection with quasi-heterodyne fringe interpolation (step-wise phase shifting) is employed and yields a resolution of 1/100 of a fringe. Automated quantitative determination of object shape and object deformation is possible in the same set-up.
