摘要: We consider how absorption-induced material heating alters the phase profile, scale, orientation, and Bragg matching of volume holograms. derive theoretical equations that prisming, lensing, mismatching occur during compare these with experimental observations. From our Bragg-mismatching considerations we show both read beam angle wavelength need to be dithered for proper compensation holograms material-heating effects. Our results indicate in volume-holographic memory systems poses a severe threat system performance. This is shown very significant Fourier plane but only moderately image
