Claim Text:
1. A measuring system for measuring a physical quantity related to one of an electromagnetic wave and a magnetic field comprising: a vibration-type actuator; a waveform generating unit configured to generate a driving waveform signal of the vibration-type actuator; an optical transmitter unit configured to receive the driving waveform signal and convert the driving waveform signal into an optical signal; an optical receiver unit configured to receive the optical signal and convert the optical signal into an alternating-current voltage signal; and a drive circuit configured to receive the alternating-current voltage signal and output a drive voltage to be applied to the vibration-type actuator, wherein the waveform generating unit and the optical transmitter unit are disposed outside a magnetic shield room, the optical receiver unit, the drive circuit, and the vibration-type actuator are disposed inside the magnetic shield room, and the optical signal is transmitted between the optical transmitter unit and the optical receiver unit.
