ABSTRACT:
A linear light source for a film scanner includes means for generating an intense beam of light and an elongated cylindrical integrating cavity having diffusely reflective walls, and defining an input port through which the intense beam is introduced into the cavity and an output slit parallel to the long axis of the cylindrical integrating cavity to emit a uniform line of light.
