Paper Abstract

We propose a new contouring method based on sending picosecond pulses toward a test object in such a sequence that if the object has the wanted shape all the scattered light arrives simultaneously to a detector. The result will be that the shortness of the detected pulse is a measure of the likeness between a holographically recorded master object and the test object.
