摘要： The present disclosure provides an optical waveguide lens, a head-up display system, and a vehicle. The optical waveguide lens includes: a lens body including a first surface and a second surface opposite to each other in a first direction, a grating structure arranged on the lens body and including an incidence grating and an outgoing grating, and a reflective layer arranged on the lens body and on the first surface. The incidence grating is arranged on the first surface, and the outgoing grating is arranged on the second surface. The reflective layer aligns with the outgoing grating in the first direction. The reflective layer can reduce the risk of light leaving the lens body from portions without grating, thereby increasing the intensity of outputting light of the optical waveguide lens, and improving the imaging effect of the head-up display system and the interaction experience between the user and the vehicle.

摘要： A multibeam backlight and multiview display employ a filling fraction of a diffraction grating to control diffractive scattering efficiency. The multibeam backlight includes a light guide configured to guide light and a plurality of multibeam elements, a multibeam element of the multibeam element plurality including a diffraction grating. The multibeam element is configured to diffractively scatter a portion of the guided light out of the light guide as directional light beams having different directions corresponding to different view directions of a multiview display. A filling fraction of diffractive features within the diffraction grating is configured to control a diffractive scattering efficiency of the multibeam element. The multiview display further includes an array of light valves configured to modulate the directional light beams to provide a multiview image. The filling fraction may be a ratio of diffractive features to filling features within the diffraction grating.

摘要： Among other things, we describe systems and method for validating sensor calibration. For validating calibration of a system of sensors having several types of sensors, an object may be configured to have a substantially reflective portion such that the sensors can isolate the substantially reflective portion, and their sensor data can be compared to determine, if the detected locations of the substantially reflective portion by each sensor are aligned. For calibrating a system of sensors, an object having known calibration features can be used and detected by each sensor, and the detected data can be compared to known calibration data associated with the object to determine if each sensor is correctly calibrated.
