Abstract: A light source illuminates a film stage through a magnifying lens that is selectively transmitted to a photodiode array over a first path including a mirror and pellicle and a second path including the first mirror and the pellicle, a selectively movable second mirror, third and fourth mirrors, a first lens element between the second and third mirror and a second lens element between the third mirror and the pellicle providing a reduction of three. Relay optics between the pellicle and a fourth mirror provides an image of the film stage on a screen. The column of 1024 diode detectors are electrically scanned to provide one dimension of a rectangular scan of the image and mechanically displaced to provide the other scan dimension. The output of the photodiode array is coupled to a recording system that may be analog or digital to record an electrical representation of the image on the film stage.
