Beschreibung
Zusammenfassung:	A system is disclosed for monitoring and controlling the deflection of turbine blades (22) of a wind turbine (10). The system includes a passive position detecting apparatus (46) and a controller (36). The passive position detecting apparatus (46) may be configured to acquire and transmit data relating directly to a position of at least one of the turbine blades (22). The controller (36) may be configured to receive the data from the passive position detecting apparatus (46) and compare such data to a known position reference to determine turbine blade deflection.
