Abstract

The recording characteristics of DuPont's HRF-150 photopolymer film are described. The application of these films for data storage using the 3-D holographic disk architecture is presented. The required system's bandwidth due to the photopolymer's limited thickness is shown to be the limiting factor of the storage capacity of these thin films and not the material's dynamic range. A new multiplexing method (peristrophic multiplexing) that significantly increases the film's capacity and changes the limiting factor from system bandwidth to material dynamic range is presented.
