Abstract
We studied the influence of the beam ratio and intensity on the optical qua lity of the transmission hologram images of diffuse objects stored in a pho topolymer and reconstructed in real time. The signal-to-noise ratio and the diffraction efficiency were used as measures of the optical quality. We ob tained a signal-to-noise ratio of 0.94 with a diffraction efficiency of 13% for a beam ratio of 20 and an intensity of 1.2 mW/cm(2). (C) 1999 Optical Society of America.
