A spatial pixel clock synchronization system with jitter correction for an optical scanning system having a continuously running pixel clock source, start of scan and end of scan split photodetectors, circuitry for producing signals proportional to the respective light exposures of the halves of said photodetectors, and circuitry, including a switched filter circuit with two storage elements for each facet of the polygon of the system, for generating from said exposure signals a frequency correction signal for the pixel clock source.
