摘要
On the basis of the idea that signal gratings have a faster formation rate than noise gratings and signal gratings have a slower erasure rate than noise gratings under the same erasing beam, we report a new technique to suppress or eliminate the noise in image processing in photorefractive crystals. A general theoretical analysis and experimental results in LiNbO 3:Fe crystals are given.
