Waveguide for head-up-display system with collimating input beam
A recently granted patent (Publication Number: US11852817B2) discloses a novel waveguide design for optical systems, particularly for head-up displays. The waveguide comprises a top surface with a specific curvature and a bottom surface designed to receive light from an input beam reflected downwards from the top surface. The bottom surface includes a first portion to confine the input beam within the waveguide structure and a second portion to collimate the beam for projection through a combiner, resulting in an image appearing at infinity. Importantly, the bottom surface features a distinct curvature from the top surface, enhancing the functionality of the waveguide.
Furthermore, the patented waveguide design incorporates unique features such as multiple convex profiles on the bottom surface, enabling the conversion of uncollimated images into collimated ones when coupled to an image source. The method of constructing the optical system involves shaping both the top and bottom surfaces of the waveguide to specific curvatures, ensuring efficient light transmission and image projection. Additionally, the seamless junction point between the first and second portions of the bottom surface eliminates air or gluing gaps, enhancing the overall performance of the waveguide. The innovative design aims to reflect and collimate input beams without the need for additional optical elements like injection gratings, diffractive elements, or holographic optical elements, simplifying the construction process and improving the display quality.
