Fiber-Coupled Optical Microphones
Motivated by the advantages of optical sensors, like immunity with respect to EMI/RFI and electrically isolated realization, today´s fiber- and micro-optics technology enables the manufacturing of sensitive optical microphones. In the first part of this article a short review of applicable sensing principles is given and pros and cons for realization are discussed. In the second part design, manufacturing and characterization for two fiber-coupled optical microphones employing optical sampling of a membrane are presented.
