Photopolymers and nanocomposites for sensing, photopatterning, and fabrication of holographic optical elements
Photopolymers are used in two types of holographic sensing. In one type the hologram changes its properties (diffraction efficiency or spectral bandpass) with change in environmental conditions or in the presence of an analyte. In another the formation of a holographic grating provides detection of the analyte. The thickness of such photopolymers may be spatially modulated by patterned light at spatial frequencies up to more than 1000 lines/mm. We also investigate the use of such materials for optical device fabrication including solar energy concentration.
