Abstract
An optical system, including an input aperture, an output aperture, and at least first and second light transmitting substrates. Each substrate has two major surfaces parallel to each other and at least one slanted edge. An input element couples light waves impinging on the input element into the light-transmitting substrates for effecting total internal reflection inside the light-transmitting substrates. An output element couples light waves out of the light-transmitting substrates. A major surface of the first light-transmitting substrate is optically attached to a major surface of the second light-transmitting substrate defining an interface. For each of the light-transmitting substrates, light waves coupled inside the substrate by the input element are substantially totally internally reflected from the interface plane.
