摘要：
Energy transfer between two laser beams writing a volume hologram in a photorefractive polymer composite is applied to video-rate optical processing applications. A net increase in image intensity as high as a factor of 37 can be observed within one video frame time (33 ms) using a total bean intensity of 1 W cm(-2) and 77 V mu m(-1) applied electric field. Moving object detection (novelty filtering) is also demonstrated. (C) 2000 American Institute of Physics. [S0003-6951(00)04523-X].
