Title:
ILLUMINATION SYSTEM FOR A FILM SCANNER
Document Type and Number:
WIPO Patent Application WO1991006034
Kind Code:
A3
Abstract:
An illumination system for a film scanner is disclosed which comprises a light source and optics for providing a line of light on a film. Light transmitted through the film is imaged onto photosensor elements such as CCD arays. In order to obtain a high quality electronic image, a xenon light source is used, color filters are included in the system to control the spectral content of the light provided to the film gate, and an integrating cylinder is used to provide a line of diffuse light on the film.
