Abstract
A system and method relating to the measuring of torque in a rotating shaft is provided. An optical torque sensing system comprises a rotating shaft, wherein a sleeve of photo-elastic material overlays a portion of the shaft. A light emitting component delivers light into the photo-elastic material, wherein the light delivered by the light emitting component is directed through the photo-elastic material along an axis of the rotating shaft. A capturing component captures the light that exits the photo-elastic material. The exiting light comprises fringe pattern data, and a computing system computes torsion strain of the shaft based at least in part on the fringe pattern information

9. A system that monitors a structure associated with a motor, comprising:
-
a layer of photo-elastic material that substantially surrounds the structure;
a light source that emits a beam of light into the layer;
a light detector that captures a light ray exiting the layer, the exiting ray having at least one of mechanical degradation and alignment characteristics relating to the structure;
an analyzer component that analyzes the received ray of light to determine the characteristics of the structure; and
a control component that can implement correction procedures to the structure. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
