Abstract:
1. A system for monitoring load-related parameters of a rotor blade of a wind turbine, the system comprising: a plurality of reflective targets positioned within the rotor blade, each of the plurality of reflective targets including a unique visual identifier; a light source configured to illuminate the plurality of reflective targets; a sensor configured to detect light reflected from the plurality of reflective targets; and a controller communicatively coupled to the sensor the controller being configured to identify the unique visual identifier of each of the plurality of reflective targets based on the light detected by the sensor and determine a current position of each of the plurality of reflective targets based on the light detected by the sensor, wherein the controller is further configured to compare the current position to a baseline position or each of the plurality of reflective targets in order to determine a load-related parameter of the wind turbine.
