摘要： PURPOSE: To conduct a multiple-point measurement, reduce the number of continuation cables, and improve noise resistance by providing a piezoelectric vibrator and an oscillation circuit and modulating transmission light or reflection light due to the vibration of the piezoelectric vibrator in response to the fluctuation of the amount of process. CONSTITUTION: A piezoelectric vibrator 2a vibrates by to the application of a voltage. It vibrates periodically so that both surfaces slide mutually in different directions in the case of the thickness slide vibration, thus enabling the position of a pin hole to move in the up-and-down directions for the vibration period from a light axis. When the pin hole deviates from a light axis, light emitted from an optical fiber 5a for transmitting light passes through the pin hole and cannot reach an optical fiber 5b for receiving light. Therefore, the quantity of light which the fiber 5b can transmit is periodically modulated for each 1/2 of the dialing period of the vibrator 2a for the incidence light with a constant quantity of light. On the other hand, the piezoelectric vibrator performing expansion motion also achieves the same effect since the pin hole periodically moves similarly. Then, an oscillation frequency changes depending on the change in the amount of process in, for example, temperature and pressure to be measured.
