Abstract:
A control system includes a mirror controller generating horizontal and vertical mirror synchronization signals for a mirror based upon a mirror clock signal. Laser modulation circuitry generates horizontal and vertical laser synchronization signals as a function of first and second laser clock signals and generates control signals for a laser that emits a laser beam that impinges on the mirror. First synchronization circuitry receives the horizontal mirror synchronization signal and the horizontal laser synchronization signal, and modifies generation of the first laser clock signal to achieve alignment between the horizontal mirror synchronization signal and horizontal laser synchronization signal. Second synchronization circuitry receives the vertical mirror synchronization signal and the vertical laser synchronization signal, and modifies generation of the second laser clock signal to achieve alignment between the vertical mirror synchronization signal and vertical laser synchronization signal.
