摘要

In almost all cases, vibration will nullify photorefractive induced effects and thus provide no benefit for us. This paper shows that we can make use of vibration to eliminate the effect of one grating and retain the effect of the remaining gratings in a multiple grating environment, such as those created via multiple two-wave mixing. If the two grating periods are different, this type of elimination is equivalent to spatial frequency filtering. We report here the first results on real-time spatial frequency filtering for the gratings formed via two-wave mixing within photorefractive crystals.
