Patent ID: 7271938

Claim:
An optical scanning apparatus, comprising: a light modulation mechanism including at least one light modulation device including a plurality of light modulation elements and configured to emit modulated light, the plurality of light modulation elements being arranged in a single-dimension formation in a first direction orthogonal to a light axis of the modulated light; a light imaging mechanism configured to receive the modulated light from the light modulation mechanism as light of an object and to transfer the light of the object to form an image of the object in a single-dimension formation on an image screen; a light deflecting mechanism configured to deflect the light of the object transferred from the light imaging mechanism in a direction orthogonal to the first direction and to the axis of the light; and a light scanning mechanism disposed on a passage of the light deflected by the light deflecting mechanism and configured to scan the light deflected by the light deflecting mechanism, wherein the light scanning mechanism includes means for reducing an image surface distortion caused by the light deflecting mechanism.
