Abstract
A 3D-interferometer equipped with four different directions of object illumination has been developed to analyze quantitatively in a first step the object surface shape and the interferometer geometry used as well as in a second step the displacement or vibration amplitude fields of mechanically loaded elements. The combination of the interference phase evaluation by digital image processing leads to a justifiable calculation time and a higher accuracy of the measuring results. First experience are described by example of synthetic interferograms concerning the determination of the object shape and the measuring accuracy of a definite rigid body displacement. Besides that, the measurement of the vibration amplitude field of an ultrasonic transducer is outlined.
