OPTICAL SHAFT TWIST ANGLE MEASUREMENT METHODS AND SYSTEMS

A system includes a shaft and a light path surface coupled to or integrated with the shaft. The light path surface is displaced as a function of twist angle at a point along the shaft. The system also includes a sensor configured to measure the light path length that varies according to displacement...

More Information
Summary:A system includes a shaft and a light path surface coupled to or integrated with the shaft. The light path surface is displaced as a function of twist angle at a point along the shaft. The system also includes a sensor configured to measure the light path length that varies according to displacement of the light path surface. The system also includes a processing unit that determines a twist angle value for the point along the shaft based on the measured light path length.
