Paper Abstract

We use the bacteriorhodopsin film as a real-time large- aperture high-resolution holographic material to demonstrate its potential as a dynamic recording and imaging medium. The imaging reflectivity is found to be linearly proportional to the reading light intensity provided that the hologram is readout by short laser pulse. The bi-exponential behavior of the recording process is related to the intensity modulation of the illumination. An image resolution of 80 lines/mm and a space-bandwidth product of approximately 2 X 106 are obtained with a phase conjugate reflectivity of above 30%.
