    Abstract: An example method includes obtaining log data descriptive of an exemplar action of an exemplar vehicle in an environment, the exemplar action occurring in an initial state of the environment; determining, using the operational system, a planned action for a simulated vehicle in the initial state of the environment; simulating an SUT state of the environment resulting from the simulated vehicle executing the planned action in the initial state of the environment and an actor performing an actor action subsequent to the planned action and an exemplar state of the environment resulting from the simulated vehicle executing the exemplar action in the initial state of the environment and the actor performing the actor action subsequent to the exemplar action; determining a test score based on the SUT state and a reference score based on the exemplar state; evaluating the operational system based on the test score and the reference score.

    Abstract: A light detection and ranging (LIDAR) system may include a laser configured to output a beam, an amplifier and a plurality of splitters. The amplifier may generate, based on the beam, a plurality of amplified optical signals that are respectively associated with a plurality of phases. The plurality of splitters, coupled between the amplifier and a plurality of outputs, may receive the plurality of amplified optical signals, generate, at a first point of time, a first combined optical signal of the plurality of amplified optical signals at a first output of the plurality of outputs with no optical signal at remaining outputs of the plurality of outputs, and generate, at a second point of time, a second combined optical signal of the plurality of amplified optical signals at a second output of the plurality of outputs with no optical signal at remaining outputs of the plurality of outputs.

    Abstract: A LIDAR assembly defining a horizontal axis and a vertical axis is provided. The LIDAR assembly includes a LIDAR unit. The LIDAR unit includes a housing defining a cavity. The LIDAR unit further includes a first plurality of emitters disposed within the cavity and a second plurality of emitters disposed within the cavity. Each of the first plurality of emitters is configured to emit a first laser beam at a first wavelength. Conversely, each of the second plurality of emitters is configured to emit a second laser beam at a second wavelength that is different than the first wavelength. The LIDAR assembly includes an optic positioned outside of the housing. The optic is configured to optically act on the first laser beam and the second laser beam in a different manner to widen a field of view of the LIDAR unit along the vertical axis.

    Abstract: The present disclosure is directed to generating vehicle motion corridors for use in generating autonomous vehicle paths. In particular, a computing system can access map data for a geographic area and sensor data for the geographic area around an autonomous vehicle. The computing system can identify, based on the map data and the sensor data, object data describing a position and a size of one or more objects in the geographic area of the autonomous vehicle. The computing system can access path data describing a nominal path through the geographic area. The computing system can determine a plurality of corridor segments associated with the nominal path. The computing system can generate a vehicle motion corridor by aggregating the plurality of corridor segments, wherein the vehicle motion corridor defines an area in which the autonomous vehicle can travel without colliding with the one or more objects.
