Paper Abstract

Image plane digital holography is used to evaluate the 3D vector components and object contour of a dynamically moving object. Pulses from a Q-switched ruby laser are used to record image plane holograms on the faceplate of a CCD camera, to be later digitally reconstructed. Three different illumination directions are used to get displacement information along three different sensitivity vectors. The latter are combined into a 3D resultant displacement vector for every object point. To compete the full 3D analysis the object contour is measured with the two-wavelength method. Data for contour and 3D-displacement are combined and displayed.
