Abstract
We describe the real-time measurement of the phase shift between the light interference pattern and a volume holographic grating recorded in dry photopolymers. The time evolution of the refractive index modulation including its magnitude and phase shift is measured for one-component and nanoparticle-dispersed photopolymers. It is confirmed that phase shifts in nanoparticle-dispersed photopolymers depend on the magnitude of the refractive index of nanoparticles relative to that of polymerized monomers.Keywords
