Abstract
Certain embodiments of the invention may include systems and methods for measuring turbine blade vibratory responses. According to an example embodiment of the invention, a method is provided for measuring a vibratory response of a plurality of turbine blades. The method can include mounting an optical probe comprising at least one probe tip optical surface, wherein the at least one probe tip optical surface is substantially parallel to within about +15 or about −15 degrees with respect to a trailing edge surface of at least one of the plurality of turbine blades, directing light towards a trailing edge surface of at least one of the plurality of turbine blades, receiving reflected light from the at least one of the plurality of turbine blades, and determining relative position of the at least one of the plurality of blades based at least in part on the reflected light.
