Paper Abstract

The Harris Corporation has been involved in the independent testing and evaluation of transparent electrophotographic films for application to high performance data recording. Various materials have been evaluated for holographic and spot recording in the past with primary recommendation given to silver halide films, which possess the key characteristics of excellent exposure sensitivity, diffraction efficiency, and signal-to-noise ratio. Transparent electrophotographic film however, has evolved into a close competitor for silver halide's position with respect to high resolution data recording. This competition is the result not only of improvements in the microimaging characteristics of transparent electrophotographic films, but also of their inherently fast in-line processing capability to produce the final archival image within seconds, convenient daylight handling, and updateability. Experimentally however, each transparent electrophotographic film tested operates via an individual mechanism characteristic to its composition. A materials evaluation breadboard was designed to provide basic characterization of image quality and image stability parameters. The design included recommended processing stations which were supplied by each film manufacturer for imagewise deposition of high resolution toner particles. The results of this independent evaluation includes information on the sensitometry, diffraction efficiency and signal-to-noise ratio as a function of spatial frequency, and microimaging characteristics. This paper is an extension of a recent paper presented at the SPIE conference in August 1979 entitled: Tranparent Electrophotographic Film for High Resolution Holographic Recorders.
