The Video-to-Film Color Image Recorder is a recording system which permits precise. The Color Recorder is capable of recording a 9500 x 9000 matrix of picture elements, whereas the maximum resolution of the RBV Camera Sub- system, for example, is approximately 4,500 TV line
A rotating, multifaceted spinner mounted on a translating carriage is utilized to generate the precision raster. After the three modulated beams have been conbined, the composite beam is expanded and focused by a catadioptric lens system (shown in Figure 3) such that it fills two facets of the spinner that folds the converging bundle and scans it across the recording format. In addition to the pictorial information contained in the video signals, the Recorder also has facilities to record an alphanumeric data field of 512 characters (8 rows of 64 characters) composed of any of 42 characters selected by the data processing system. The recording format is comprised of three fields as shown in Figure 4. The 7.5-inch square Picture Format depicted allows the RBV images, to be presented at approximately a 1 : 1,000,000 scale.
