Abstract:
1. A high speed pulse width modulation system for driving a linear array spatial light modulator, comprising: a) a pixel-serial data source providing at least one or more pixel-serial input data streams; b) a clock for providing a fundamental system clock signal; c) a phase shifter providing at least one or more clock signals that are phase-shifted versions of the fundamental system clock signal; d) a serial-to-parallel converter for converting the at least one or more pixel-serial input data streams into one or more pixel-parallel data streams; e) a decoder for decoding data of a single input pixel into at least two or more related pulse width modulation (PWM) signals, wherein the at least two or more related PWM signals are synchronized to different edges of the fundamental clock signal and the at least one or more phase-shifted clock signals; and f) a circuit for combining the at least two or more related PWM signals into a single PWM signal capable of driving one of a plurality of inputs on a linear array spatial light modulator.
