A novel apparatus for use in generating a scan timing signal in a laser raster scanner includes an optical diffuser positioned to receive a scanned reference beam through a reference mask. The diffused, modulated reference beam is presented to an array of photodetectors. The number of photodetectors in the array is selected to be sufficient so that at least two photodetectors receive the diffused modulated reference beam simultaneously as the reference beam is scanned along the reference mask.
