A scanning assembly for a detection system for a vehicle has a scanning fixture including a first mirror. The scanning fixture is attached to a first pivot. A reflective surface of the first mirror provides a first field of view between the detection system and a surrounding environment. A central member has a first end attached to the first pivot and a second end attached to a second pivot to couple the first pivot to the second pivot. A base is configured to attach the scanning assembly to the vehicle. The base is further attached to the second pivot. The scanning fixture is coupled to the base exclusively through attachment of the first pivot to the second pivot via the central member, the second pivot in turn being attached to the base.
