| 摘要 |
The invention relates to a lighting arrangement for a film scanner, comprising a line sensor, a light source and an optical device for generating a diffuse line shaped illumination on the film. The optical device comprises a cross-section transducer (16) made from a bundle of optical fibres, comprising a flat cross-section on a light input surface (15) and a line shaped cross-section on a light output surface (18), in addition to an integration bar (19), which conducts light to the film from the light output surface of the cross-section transducer (16). |
