Increased Optical Resolution from a Sampled Wavefront

Not Accessible

Your library or personal account may give you access

Abstract

A holographic arrangement is suggested for obtaining samples or patches of the wavefront scattered from a laser illuminated object. Each sample is a hologram formed by using a specular reflection from the object to generate an internal reference. This arrangement permits the use of very short laser pulses having only a few meters of coherence length. The use of polarization filtering enables one to eliminate the specular reflections in the reconstruction.
