Abstract:An optical readout system and the method for angular position detection of the spin axis of superconducting rotor are studied. The influence of heat influx due to optical illumination on rotor under operating conditions is discussed The analysis results show that this optical readout system could be used at the cryogenic temperature for angular position detection of the spin axis.
Keywords:superconducting rotor  photoelectric sensor  optical readout system
