1. A system of a wind turbine, the system comprising:
a hub, the hub comprising a non-rotating component of a pitch bearing;
a rotor blade comprising a blade root, the blade root comprising a blade root end and a rotating ring component of the pitch bearing affixed to the blade root end;
a plurality of non-contact displacement sensors operably facing the rotor blade and fixed directly or indirectly to the hub;
a respective reference plane associated with each of the plurality of non-contact displacement sensors, the respective reference planes defined by the rotor blade or a component that moves with the rotor blade as the rotor blade moves relative to the hub;
wherein each of the plurality of non-contact displacement sensors detects relative movement between the respective reference plane and the hub without being physically connected to the component defining the respective reference plane; and
wherein the plurality of displacement sensors are mounted opposite to and facing their respective reference plane.
