Real-Time Holographic Recording of Reflection Gratings in Photopolymer Materials with Varying Mean Refractive Index and Density

摘要

Holographic recording of reflection gratings in photopolymer materials with varying mean refractive index and shrinkage in real time is studied. Conditions for matched displacement of the interference field and the phase planes in a recording medium are determined, which provides recording of reflection gratings with a diffraction efficiency greater than 95% and a spatial frequency greater than 6000 mm1.
