We report on the recent advances made by our groups in the technology and applications of Holographically formed Polymer Dispersed Liquid Crystal (HPDLC) devices. In this paper we will briefly review some of the basic operating principles of HPDLC devices and their salient features as applied to display and image capture applications. The usability of HPDLC films in displays is enhanced by incorporating diffusion into the films. The photopic reflectance and reflection bandwidth of an HPDLC device can be improved by stacking multiple films of HPDLC material between one set of electrodes. HPDLC mirrors can be used to advantage in an electronic image capture system.
