Abstract

A two-step method has been developed to obtain a diffuse-object hologram with high efficiency and low noise. In the first step a silver-halide gelatin hologram with high signal-to-noise ratio is obtained. In the second one, this hologram is copied onto dichromated gelatin using a partially coherent source. Results are compared with those obtained directly in dichromated gelatin using coherent light from an argon laser.

Diffraction efficiency and signal-to-noise ratio as functions of exposure from holograms on DCG, obtained with the two-step method at 405 nm (solid lines) and directly at 488 nm (broken lines). In both cases the holograms are recorded with a reference beam to object beam intensity ratio of 5:1, and the readout measurements are made at 633 nm.
