Abstract
An apparatus is disclosed. For example, the apparatus may include an array of a plurality of micromirrors, a light source to provide a light input at a near symmetric angle relative to a normal angle of each one of the plurality of micromirrors in the array, and an optic adjuster to adjust an off-axis light output of the plurality of micromirrors in the array when the plurality of micromirrors is in an on-state.
