Abstract
The display properties of previously described strain-biased ferroelectric-photoconductor devices that operate in a transmission projection mode can be improved by operating them in a double-pass or reflection mode in which the reading light is reflected off an opaque interface between the ceramic and the photoconductor. Such an arrangement offers better resolution (because of the thinner ceramic), isolation between reading and writing light, and greater flexibility in the choice of photoconductor, which need not be transparent to the reading light. Simple reflection mode structures have been fabricated that use either PVK or CdS photoconductive layers and show a resolution of 250 lines/in.Keywords
