CPC H04N 9/3135 (2013.01) [H04N 5/06 (2013.01); H04N 9/3155 (2013.01); H04N 9/3161 (2013.01); H03K 21/40 (2013.01); H03L 7/08 (2013.01)] | 18 Claims |
1. A control system for a laser scanning projector, comprising:
a mirror controller configured to generate horizontal and vertical mirror synchronization signals for an oscillating mirror apparatus based upon a mirror clock signal;
laser modulation circuitry configured to:
generate horizontal and vertical laser synchronization signals as a function of first and second laser clock signals; and
generate control signals for a laser that emits a laser beam that impinges on the oscillating mirror apparatus;
first synchronization circuitry configured to:
receive the horizontal mirror synchronization signal from the mirror controller;
receive the horizontal laser synchronization signal from the laser modulation circuitry; and
modify generation of the first laser clock signal so as to achieve alignment between the horizontal mirror synchronization signal and the horizontal laser synchronization signal; and
second synchronization circuitry configured to:
receive the vertical mirror synchronization signal from the mirror controller;
receive the vertical laser synchronization signal from the laser modulation circuitry; and
modify generation of the second laser clock signal so as to achieve alignment between the vertical mirror synchronization signal and the vertical laser synchronization signal.
