ABSTRACT:
An optical scanner assembly for exposing an image on a piece of photosensitive film positioned within an internal drum type exposure assembly. The optical scanner assembly is part of a laser imaging system suitable for use in a medical imaging system. The optical scanner assembly includes a laser mechanism for producing a laser beam representative of the image to be exposed on the photosensitive film. A first lens system is provided for shaping and focusing the laser beam in a first direction, including a long, flexible cylinder lens. A second lens system is provided for shaping and focusing the laser beam in a second direction, including a second cylinder lens oriented generally perpendicular to the long, flexible cylinder lens. A scanning and directing system is provided for directing the laser beam and scanning the laser beam across the photosensitive film in an image-wise pattern, including a rotating scanner mechanism, wherein the long, flexible cylinder lens is located between the rotating scanner mechanism and the photosensitive film.
