Abstract

PURPOSE:To transmit feeble information accurately without any bad influence of external noises by providing transmission systems for a reference signal and an information signal where temperature fluctuates much due to a high voltage and high magnetic flux. CONSTITUTION:The information signal of signal source 1 at place 14 of violent fluctuations of temperature is converted by FM modulator 7a of center frequency f0, whose output is input to optical fiber 10a by way of driving circuit 8a and LED9a. Further, the input side of FM modulator 7b provided for a reference signal at place 14 is grounded and its output voltage of center frequency f0 is input to optical fiber 10b by way of driving circuit 8b and LED9b. Profected outputs of respective optical fibers are supplied to differential amplifier 13 by way of photodiodes 11a and 11b, amplifiers 12a and 12b and F.V converters 3a and 3b. Therefore, an information voltage under no influence of a drift of temperature can be led out of amplifier 13 being amplified as fixed.
