The principle of incoherent-to-coherent conversion is demonstrated in several photorefractive oxide crystals using a self-pumped phase-conjugator geometry. Resolution in excess of 30 line pairs/mm has been obtained for writing beams of a few milliwatts of power. The combined read/write function for a single frame showed a time response of approximately 140 ms at an intensity of 1 W/cm2 for the crystals used in these demonstrations.
