摘要： A laser scanner which includes a light source which emits a light beam and a scanning mirror rotatable about an axis which reflects the light beam through a tilted protective window toward a scanning area and which directs return light from objects toward receiving optics. The laser scanner may include a collecting mirror which receives the return light, and an interference filter disposed between the collecting mirror and the scanning mirror. The window may include an anti-reflective coating which reduces reflection of internally scattered light. The tilted window may direct the reflective component of internally scattered light into a zone where an energy light absorber is present. A bulkhead system which may include a separation baffle may be provided to prevent light incident on the interference filter at an angle which is below an acceptance angle of the interference filter.

摘要： A LiDAR sensor can include a laser, a directional sensor, a window, an electromagnetic pulse receiving sensor, and a processor. The laser can be configured to emit a narrow electromagnetic pulse. Further, the directional sensor can be configured to measure the direction of the narrow electromagnetic pulse emitted by the laser. The narrow emitted electromagnetic pulse can pass through the window. The pulse can then be reflected by at least the window and an object external from the LiDAR sensor, creating at least two reflected pulses. The electromagnetic pulse receiving sensor can be configured to measure the two reflected pulses resulting from the narrow pulse emitted by the laser. The processor can be configured to receive information from the sensors, indicating a position of the object relative to the LiDAR sensor. Further, the processor can be configured to measure the intensity of the pulse being reflected by the window.

摘要： Methods and systems are disclosed for determining sensor degradation by actively controlling an autonomous vehicle. Determining sensor degradation may include obtaining sensor readings from a sensor of an autonomous vehicle, and determining baseline state information from the obtained sensor readings. A movement characteristic of the autonomous vehicle, such as speed or position, may then be changed. The sensor may then obtain additional sensor readings, and second state information may be determined from these additional sensor readings. Expected state information may be determined from the baseline state information and the change in the movement characteristic of the autonomous vehicle. A comparison of the expected state information and the second state information may then be performed. Based on this comparison, a determination may be made as to whether the sensor has degraded.

摘要： Method and system for managing data about a road condition and providing the data to vehicles includes generating information using a sensor system at a first vehicle about a condition of a surface on which the first vehicle is travelling, wirelessly communicating the surface condition information to an off-vehicle location using a first communications system on the first vehicle, and determining a position of the first vehicle using a position determining system, e.g., on the first vehicle. The surface condition information from the first vehicle is associated with the determined position of the first vehicle, to know the location at which the surface condition information is pertinent. Via a second communications system on a second vehicle, the surface condition information from the off-vehicle location is received based on location of the second vehicle, so that the operator of the second vehicle is thereby notified of a potentially hazardous road surface condition.
