FROSTED PHOTOPLASTIC
Abstract
Major accomplishments to date can be summarized as follows: (1) Photoreceptor: The preferred structure is a thin SeTe interface layer on a conductive-glass substrate with a selenium charge-storage overlayer. This plate has shown a resolution capability of 147 1p/mm by xero graphic development. Response is roughly panchromatic with efficiency ranging from approximately 60% in the blue-green region of the spectrum to approximately 4% at 8000 angstroms. Sensitivity to daylight exposure s 3 to 6 times that of conventional selenium plates. In preliminary imaging tests using the charge-transfer/frost system, image defects due to photo conductor non-uniformities were undetectable. Several selenium-tellurium plates with closely similar electrical characteristics have been made. (2) Methods: The effects of a number of variables such as time, temperature, film-thick ness, etc. on the characteristics of frost development have been determined in sufficient detail to guide in the design of the camera-developer device.
