Abstract
An image display apparatus comprises an image display unit capable of producing and displaying not an image itself but a Fourier-transform image of the image, and a light transmission unit for focusing the Fourier-transform image produced and displayed on the image display unit on a pupil face of an observer's eye and producing an original image on the retina of the eye. The light transmission unit includes a lens and an eye lens such that an image-side focal position of the lens coincides with an object-side focal position of the eye lens. A mask is situated at the object-side focal position of the eye lens to determine the range and shape of a visual field. The image display unit is situated at an image-side focal position of the lens, and the pupil face of the observer's eye is alinged at an image-side focal position of the eye lens.
