The photographic plate was fabricated from redsensitive photopolymer on the ITO glass for the first time. The holographic grids were made by double path-interference using semiconductor laser ( =635nm) as light source. The holographic grids and polymer dispersed liquid crystal (PDLC) were pressed together to get a new optical grating with a grating constant of 521.6nm. We measured its e-o parameters including the response time and the diffraction efficiency etc. It is shown that the structure… CONTINUE READING
