Abstract
A spatial light modulator outputs modulated light including: modulated first light when the spatial light modulator receives first light; and modulated second light when the spatial light modulator receives second light. Projection optics project the modulated light onto: a first pixel region when a component or the spatial light modulator has a first position; and a second pixel region when the component or the spatial light modulator has a second position. The first and second pixel regions partially overlap. A pixel shifter moves the component or the spatial light modulator between: the first position when the spatial light modulator outputs the modulated first light; and the second position when the spatial light modulator outputs the modulated second light.
