摘要: A fiber optic microphone is provided for measuring fluctuating pressures. An optical probe having at least one transmitting light to a pressure-sensing membrane and receiving reflected from stretched provided. The may be high frequency response. Further, reflecting surface of the have dimensions which substantially correspond cross section probe. can made materials use in temperature environments, example greater than 1000° F. also with backplate damping motion. further provides means on-line calibration microphone.
