Abstract
An image display apparatus comprises an image display unit capable of generating and displaying a plurality of coherent point light source pairs, a light transmission unit for focusing the point light source pairs on the pupil plane of an observer's eye so that an image is formed on the retina of the eye by the effect of optical interference, a visual axis detector for monitoring the movements of the eye and detecting the visual axis direction thereof, and an image display correcting unit for restricting a distortion of the image, caused by the eye movements, within its tolerance in accordance with data detected by the visual axis detector. The image display correcting unit includes an optical member set in an optical path between the image display unit and a lens, and an optical member drive unit for tilting the optical member for a given angle in a predetermined direction.
