Abstract
A novel Electronic-Speckle-Pattern-Interferometer which is based on an endoscope camera system can be applied to handheld examinations for in-vivo minimal-invasive diagnostics. Optical fibers, endoscopic optics and an amplitude modulated cw-laser are used for illumination. A CCD-camera in combination with a fast frame grabber-system allows dynamic `on line'-image subtractions up to a frequency of 25 Hz with high fringe contrast. The influence of rigid body motions on the interference fringe pattern is compensated by a new digital processing method based on Fourier algorithms.
