Photoplastic Recording PPR is a photographic process i which images are recorded as surface deformations on a reusable photoconductive thermoplastic film. The image is developed instantaneously by heat and erased only by melting the film. The feasibility of updating information displayed by a cathode ray tube at least five times per minute was demonstrated. Sensitivity, resolving power, contrast and recording parameters such as film surface potential for sensitization, thickness, and erasure conditions were investigated. Images were schlierenprojected and image quality analyzed. Color projection of PPR images was studied. A PPR recorder was designed and constructed. Operating and servicing instructions are furnished.
