Paper Abstract

The design, fabrication, and characterization of an optical, noncontact microsystem for the measurement of torque on a drive shaft are described. The heart of the system consists of a glass integrated optical interferometer chip; ball lenses are used for collimation of measurement beams onto reflectors embedded in the shaft. The system requires no contact with and only minimal modification of the drive shaft.
