Paper Abstract

Experimental results of a high-resolution holographic imaging system using wave-front conjugation are demon-strated. Using an Argon laser operating at 488 nm with a coherence length of one meter, a hologram is formed from the information on a master mask that is imaged onto a high-resolution recording material with a photographic quality multi-element lens. The hologram is illuminated with a spatially and temporally filtered beam of light centered at 488 nm from a Hg arc lamp to construct the image of the master mask. The aberrations introduced by the imaging lens are eliminated through the process of reverse ray tracing back-through the original lens. The use of a spectrally-broad construction source reduces the effects of optical noise generated in the optical train during the construction of the image. Diffraction limited images are experimentally observed throughout the illuminated field.
