发明名称 Transparent film scanner having light source system with diffuser and reflector
摘要 A transparent film scanner having a light source with a diffuser and a reflector includes a light source for generating a primary light that is diffused by a diffuser to obtain a more uniform secondary light. The secondary light source is then reflected by a reflector to produce a tertiary light for illuminating the film. With a diffused secondary light, the distance between the reflector and the film can be reduced, thus reducing the size of the scanner.
