Undesired reflections in a photosensor array encapsulated in a glass-covered housing are reduced by including between the cover and photosensor array a solid or fluid adapted to substantially match the index of refraction of the cover.

Reducing flare in self-scanned photosensor arrays

A compact stereo light table includes a pair of high intensity spot sources on a diffusely illuminated background that are selectively diffuse or specular. There are controls for spot brightness, diameter and positioning and specular to diffuse adjustment.

Film examining with diffuse and specular illumination

A fixed drum has input, output and developing segments of aluminum to provide a cool input and output segments thermally separated from a heated developing segment maintained at substantially constant temperature. The film to be developed passes beneath a wire at high electrical potential relative to the drum to receive charge from a corona discharge that produces electrostatic forces securing the film to an endless belt that carries the film around the drum wrinkle-free. A pair of input rubber drive rollers drive the belt around the drum. The film to be processed is placed on the belt between the drive roller and drum. An output pair of metal rollers partially drain the charge from the developed film and belt and guide the film toward the exit slot. The inner surface of the belt is electrically conducting low friction tetrafluoroethylene to allow the belt to move freely around the stationary drum. The belt outer surface is silicon rubber which may be impregnated with carbon.
