Novel curved waveguide for slim head up displays

Abstract

A waveguide can include a first portion configured to confine an input beam within the structure of the waveguide, and a second portion configured to collimate the beam to be projected through a combiner, to produce an image in infinity. A method of constructing an optical system for a head-up-display can include shaping a first waveguide element such that a first portion of the waveguide is configured to confine an input beam within the structure of the waveguide, and a second portion is configured to collimate the input beam. The method can include coupling the waveguide to a combiner.
