摘要

A method has been developed for retrieving the complete angular selectivity profile of transmission holo-ngraphic gratings in one step. The method is applied to study in real time the shrinkage and changes in theneffective optical thickness of a slanted holographic grating recorded in an acrylamide-based photopolymer. Itncan form the basis of a holographic sensor of analytes that cause a thickness change in the holographic me-ndium. It can also be useful for the study and optimization of holographic recording materials and for qualityncontrol during production of holographic optical elements. © 2008 Optical Society of America
