ABSTRACT:
A scanning system (25) for controlling a scanning servo (28,30) includes a scanning signal generator (50) which generates (51) a series of square wave scan signals, a pulse signal generator which generates (52) a pattern of pulses having short durations relative to the scan signal from the first generator, the generators being synchronized, and the scan signals and pulses then being separately applied to the scanner servo (30) to control it such that the resulting scanning behavior of the servo corresponds to the scan signals modified by the pattern of pulses.
