HIGH-SPEED PULSE WIDTH MODULATION FOR LIGHT MODULATORS

摘要

A high speed pulse width modulation system for driving a linear array spatial light modulator, including: a pixel-serial data source that provides at least one or more pixel-serial input data streams; a fundamental system clock signal; a phase-shifted versions of the fundamental system clock signal; and 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. Also included is a decoder for decoding data of a single input pixel into at least two or more related pulse width modulation (PWM) signals each mutually separated by the phase-shift of the phase-shifted version of the fundamental system clocks signal and an AND gate circuit for combining the at least two or more PWM signals into a single PWM signal capable of driving one of a plurality of inputs on a linear array spatial light modulator.
