Abstract
A method is proposed for direct optical comparison of the three-dimens ional shapes of objects by light-in-flight speckle holography. The bas ic idea of this technique is to use an ultrashort laser pulse with a s hort coherence length to produce interference patterns that present a single contouring of the object. A simple experiment using plane diffu se objects was performed to verify the method. (C) 1997 Optical Societ y of America.
