Abstract
Disclosed is a method for measuring deformation of a turbine blade, the method including identifying at least one measuring point disposed on the turbine blade, retaining information pertaining to a first position of the at least one measuring point, operating the turbine blade over a period of time, measuring a spatial distance traveled by the at least one measuring point after the operating of the turbine blade over the period of time, the spatial distance being measured relative to the first position of the at least one measuring point; and determining an amount of deformation in the blade based on the measuring of the spatial distance.
