Abstract: A method for design and fabrication of holographic optical elements for a compact holographic sight is proposed. The method includes use of ray-trace software to design holographic elements having optical power using an intermediate hologram with parameters obtained through minimization of the merit function defining image quality.

Abstract: The present invention is a Substrate guided hologram that allows a wider range of optical devices based on SGHs with improved parameters such as larger NTE displays with a wider field of view, thinner substrates and more compact form factors. The Substrate-Guided Hologram of the subject invention includes a holographic lens which is positioned at an angle to and spaced from a holographic grating, with a mirror located at a diagonal to each of the lens and the grating.

Abstract: Multiple pairs of substrate-guided wave-based holograms (SGWHs) are laminated to a common thin substrate to form a transparent substrate-guided wave-based holographic CHMSL (SGWHC) that diffracts playback LED illumination over a wide angular range. This device is made pursuant to a technique that includes the steps of recording a first set of SGWHs with one setup, that upon playback, will couple and guide the diffracted light inside the substrate, and a second set of SGWHs recorded with another setup, that will diffract and couple the guided light out.

Abstract: The present application is directed to an optical system made of a microdisplay; a holographic lens; a bent, monolithic, solid light guide; and a transparent holographic grating with a wedge attached to the back. The bent optical waveguide is made from one piece of thermoplastic polymer or is made by 3D printing using thermoplastic polymer.
