Послеэкспозиционное изменение характеристик объемной решетки в полимерной голограммной среде с фенантренхиноном

Nonmonotonic changes of the diffraction efficiency and of the Bragg`s diffraction angle of volume holographic grating which have been recording in the polymeric medium with phenanthrenequinone are experimentally established in postexposure period.
