Paper Abstract

A new multisource contouring method is presented. Holographic setup for recording uses single-beam reflection holography. Between exposures the system of object and holographic plate is rotated at a small angle (Delta) i, and an M-fold exposed hologram of the object is recorded on the same plate. After development of the plate contour fringes are generated on a reconstructed object image by multipath interference. It is possible to rotate a source of irradiation or illuminate the object through the plate simultaneously by M collimated beams instead of rotation of object-plate system. The obtained contour fringes have less FWHM in M/2 times than in the two-source contouring method.
