ABSTRACT:
A high resolution scanner is disclosed which is adapted to digitally record an image from photographic film. The scanner comprises a folded integrating sphere which projects illumination on the film as the film is moved relative to the integrating sphere. Light transmitted through the film is directed to a photodetector by an optical system. In order to produce an aberration-free image on the photodetector, the illumination projected on the film is in the form of an arc, and a unit magnification optical system transmits light to a photodetector having image sensor elements arranged in an arc.
