Abstract
Image storage has been investigated with the biphotonic holographic me thod in an azo/polymer film. Experimental results show that this bipho tonic holographic storage has high spatial resolution and exhibits an image enhancement effect after blocking the noncoherent light. The mec hanism of biphotonic holographic storage is attributed to the redistri bution of cis form ate molecules induced by both coherent light and no ncoherent light.
