A high speed parallel scanning scheme is described that uses high density linear sensor arrays to convert optical images into electrical signals for computer processing or storage. By using two 1,024-element linear arrays in a staggered line and x-y translational stages, a 9- by 9-inch transparency can be scanned and digitized into 8.5 time 10 to the 7th power pixels in 1 minute. Scan time can be reduced by increasing the slew rate of the stage or by increasing the scan line by using additional arrays. Since each array produces four simultaneous video signals, the system could be utilized as an input device for a parallel processor such as the STARAN. The video signals can be multiplexed onto a single line if desired. Author
