Abstract:

The document contains a general discussion of the problem of dimensional stability of photographic films. The effects of time, temperature, humidity and chemical processing on the location of images are assessed for typical photographic emulsions coated on glass, polystyrene, polyesters, and cellulose esters. The discussion is narrowed to consideration of the ARTEMIS signal-processing problem. Handling precautions and compensating procedures aimed at minimizing information loss owing to dimensional changes are examined. It is concluded that photographic film is satisfactory for use as the signal record in photo-optical signal processing, provided appropriate choices are made of materials, environmental control, and fiducial procedures.
