ABSTRACT:
An electronic circuit is utilized to correct scan non-linearity of a raster output scanner. The circuit modulates a clock frequency to match a scan linearity error profile. Because it is a separate circuit, the exiting closed-loop clock generator does not need to be modified. The correction circuit synchronizes itself with the clock signal using a counter/subtractor phase detector, which ensures that the phase and frequency of the internal clock matches the phase and frequency of the master.
