ABSTRACT:
The present invention provides precise constant velocity linear motion for reading and writing information over an area. The present invention uses a multiple cylinder linear feed unit to move a reflective surface and control the deflection of one or more beams. One embodiment of the present invention involves use of a pneumatic/hydraulic linear feed unit with a three color laser based film scanner/recorder system. The system can convert a film image to a digitized image capable of being processed by a computer and can also convert a digitized image to a film image. Two-axis scanning of a film frame is accomplished using a single scan mirror attached to a galvanometer scanner. The scan mirror and galvanometer scanner are coupled to a custom controlled rotary head assembly. The galvanometer deflects the scan mirror in a fast scan direction to create a scanline of the laser beam. A pneumatic/hydraulic linear feed unit is used to rotate the galvanometer assembly. By rotating the head assembly, the entire galvanometer assembly is moved, resulting in displacement of the beam along a slow scan axis across the film plane.
