Abstract

See full text

A method to determine a characteristic on a turbine shaft is provided. The method includes disposing a reflective/absorptive target comprising a plurality of markings in a geometric pattern on the component. A light emitting source will then be focused onto a predetermined starting position on the target. The plurality of markings will linearly traverse across the light emitting source from the predetermined starting position. The reflected/absorbed light pulses from the plurality of markings will be detected and recorded. From the timing of the recorded light pulses, the characteristic of the component is determined. The geometric pattern comprises at least two non-parallel lines and a third line including the predetermined position. A system to determine a characteristic on a turbine shaft as well as a method to determine the torsional deflection of a turbine shaft are also provided.
