Abstract
The present invention provides an image display apparatus including a spatial light modulating element formed with a plurality of light modulating elements for each modulating light from a light source and arranged in a row or a plurality of rows, a projection optical system for forming a first image on a basis of the light modulated by the spatial light modulating element, light deflecting means for forming a second image by reflecting the first image formed by the projection optical system so as to scan the first image in a direction orthogonal to a longitudinal direction of the first image, which is a longer direction of the first image, a magnifying and projecting system for magnifying the second image and projecting the second image on a screen, and detecting means for detecting intensity of the light modulated by the spatial light modulating element and reflected by the light deflecting means via the projection optical system, the detecting means being disposed at a position that the light reflected from the light deflecting means enters without passing through the magnifying and projecting system, the position being off an optical path of the light going from the light deflecting means to the magnifying and projecting system.
