  • Head mounted imaging apparatus with optical coupling
    Patent number: 10955676
    Abstract: A head-mounted imaging apparatus includes a frame that houses a left-eye and a right-eye imaging apparatus. Each imaging apparatus forms a virtual image to an eye of an observer and includes a projector, a planar waveguide, and an optical coupler. The projector is supported by a temple member of the frame and emits a central projected light beam along a projection axis. The planar waveguide accepts the projected light beam through an input aperture and forms an expanded light beam that is output from an output aperture and directed toward the observer's eye. The optical coupler receives the central projected light beam along a first axis that is at an obtuse angle with respect to the waveguide surface, and the optical coupler redirects the central projected light beam along a second axis that is at an acute angle with respect to the waveguide surface.
