    Abstract: Embodiments describe a solid state electronic scanning LIDAR system that includes a scanning focal plane transmitting element and a scanning focal plane receiving element whose operations are synchronized so that the firing sequence of an emitter array in the transmitting element corresponds to a capturing sequence of a photosensor array in the receiving element. During operation, the emitter array can sequentially fire one or more light emitters into a scene and the reflected light can be received by a corresponding set of one or more photosensors through an aperture layer positioned in front of the photosensors. Each light emitter can correspond with an aperture in the aperture layer, and each aperture can correspond to a photosensor in the receiving element such that each light emitter corresponds with a specific photosensor in the receiving element.

  • Patent number: 11040659
    Abstract: A method displays information graphically on an image captured by a vehicular optical system. The method includes capturing the image and identifying an object in the image. The method the assigns a priority level to the object based on a predetermined criterion. The object is altered based on its priority level to create an altered object. An altered object may have a changed color, a colored halo surrounding it, or a colored object inside it. Other possible ways to alter the way the object looks are possible. The altered object is displayed in the image in place of the object on a mobile device to alert a person of its presence and the priority level associated therewith.

  • Patent number: 11041957
    Abstract: System, methods, and other embodiments described herein relate to improving observations of a surrounding environment using a light detection and ranging (LiDAR) device in the presence of highly reflective surfaces. In one embodiment, a method includes, in response to determining that a first point cloud includes an observation of an obscuring object that is highly reflective: i) emitting a scanning light beam at a scanning intensity that is different from an initial intensity of an initial light beam used to acquire the first point cloud, and ii) dynamically controlling the LiDAR device to acquire a second point cloud that omits the obscuring object. The method includes generating a composite point cloud from the first point cloud and the second point cloud that improves an observation of the surrounding environment using the LiDAR device by mitigating interference from the obscuring object.

  • Patent number: 11018637
    Abstract: Aspects of this disclosure relate to a receiver for a light detection and ranging system. The receiver includes a transimpedance amplifier that is operable in a linear mode for a range of power of light received by the receiver. The receiver can provide information about amplitude of the light outside of the range of power of the light for which the transimpedance amplifier operates in the linear mode. This information can be useful, for example, in identifying an object from which light received by the receiver was reflected.
