Detection system with reflection member and offset detection array

A detection system for a vehicle in an environment, comprising:

• a reflective member positioned along an x-y plane for rotation around a rotational axis orthogonal to the x-y plane, the reflective member having a plurality of reflective sides, each of the reflective sides extending between a first end and a second end and sloping towards the rotational axis at a slope angle different than the slope angle of at least one of the others of the reflective sides;
• a first array of light transmitters, each light transmitter configured to transmit a light beam towards the reflective member for reflection off an active reflective side of the plurality of reflective sides and into the environment;
• a first array of light receivers, each light receiver configured to receive at least one transmitted light beam that has deflected off an object in the environment before returning to the detection system and deflecting off the active reflective side;
• and
• an actuator configured to rotate the reflective member around the rotational axis to change the active reflective side to a different one of the plurality of reflective sides,
• wherein the first array of light transmitters and the first array of light receivers are offset from the reflective member with respect to the x-y plane.

• a LiDAR system having at least one light transmitter and at least one light receiver, the LiDAR system positioned below the reflective member with respect to a ground surface, an active side of the plurality of reflective sides positioned to provide a field of view between the LiDAR system and the environment;
• and
• an actuator configured to rotate the reflective member around the rotational axis to change the active reflective side to a different one of the plurality of reflective sides.
