Abstract (en)
[origin: WO2019050643A1] One example system includes a light source that emits a light beam. The system also includes a waveguide that guides the emitted light beam toward an aperture. The system also includes a lens that directs the light beam, guided by the waveguide and transmitted through the aperture, toward a scene. The lens also receives light propagating from the scene toward the lens. The lens focuses the received light into the aperture. The waveguide also guides the focused light transmitted through the aperture. The system also includes a light detector. The waveguide transmits at least a portion of the focused light out of the waveguide and toward the light detector.
