摘要： A device for transilluminating a film has a light exit emitting with a light beam for transilluminating the film, a transillumination region for guiding the film such that the light beam can transilluminate the film in the transillumination region, a film feed for feeding the film to the transillumination region and a film removal for removing the film from the transillumination region. The device moreover includes a hollow chamber with a diffusely reflecting inner surface and a light entrance opening receiving light from a light source and an exit opening, as well as an optical guide having a beam entrance end and a beam exit end. The beam entrance end is arranged such that light exiting from the exit opening of the hollow chamber at least partially enters through the beam entrance end into the optical guide.

摘要： An apparatus for transilluminating a film includes a light source emitting a light beam for transilluminating the film, a film guide for guiding the film such that the light beam can transilluminate a section of the film, a film feed for feeding the film to the film guide, and a film removal for removing the film from the film guide. The film guide has a support designed for rotation about a rotation axis running through the center of the support and a rotationally symmetric circumferential surface. The film can be supported on the circumferential surface at least with part of the width thereof over a section of the circumferential surface. The light beam generated by the light source passes through the film when the film is supported on the circumferential surface at least with part of the width thereof over a section of the circumferential surface.

摘要： To be able to scan the sprocket holes of a film with improved precision by means of a film scanner, in which a correction signal is generated for compensating picture steadiness errors, it is proposed that the light source generates light in the infrared range, and that the scanning sensor(s) is (are) sensitive in the infrared range.

摘要： A detection apparatus for detecting perforation holes of a cinematographic film comprises at least one light source, at least one scanning sensor, which is arranged so as to receive light emitted by the light source after interaction with a perforation zone of the film, and an evaluation circuit for detecting, by means of an output signal of the scanning sensor, when an edge of a perforation hole passes through between light source and scanning sensor. The light source emits light which is polarized with a first polarization and the scanning sensor is sensitive selectively to light with a second polarization.
