Abstract
An image projection apparatus includes a one-dimensional spatial light modulating element and a polygon scanner having four or five mirror facets. The polygon scanner scans a light beam modulated by the one-dimensional spatial light modulating element in a direction that is substantially perpendicular to the length direction of the one-dimensional spatial light modulating element so as to display an image.
