Direct object-shape comparison by light-in-flight speckle interferometry

Not Accessible

Your library or personal account may give you access

Abstract

A method is proposed for direct optical comparison of the three-dimensional shapes of objects by light-in-flight speckle holography. The basic idea of this technique is to use an ultrashort laser pulse with a short coherence length to produce interference patterns that present a single contouring of the object. A simple experiment using plane diffuse objects was performed to verify the method.
