Abstract
An illumination apparatus generates illumination light. A patterning device includes a digital micromirror device (DMD) configured to spatially modulate and reflect the illumination light according to a pattern signal. A DMD controller generates the pattern signal. The DMD controller generates a refresh pattern signal for repeatedly turning on and off micromirrors in a period in which the DMD is set to the enable state and the illumination light is turned off.
