Abstract

For the evaluation of 3-D displacement and strain of non-plane objects by means of double exposure holographic interferometry, errors induced by defocussing of the object surface and distortion due to perspective have to be taken into account. The importance of these errors is discussed. Numerical methods for correction and experimental results are presented.
