Optical image projector for projecting an erect positive image of unity magnification and for minimizing degradation in resolution

摘要

An optical image projector includes an array of optical elements which projects an erect positive image of an object onto an image receiving surface which is not parallel to the plane of the object. The array, the plane of the object and the image receiving surface are disposed in a manner such that the angles formed between the plane of the object and the image receiving surface on one hand and the optical axis of the array on the other are equal to each other and are disposed on the same side of the optical axis.
