  • What are fiber optic acoustic fingerprint sensors

    What are fiber optic acoustic fingerprint sensors

    Fiber optic acoustic sensors are an innovative technology that utilizes the interaction between light and sound to measure acoustic waves. This technique leverages the unique properties of optical fibers, which are capable of transmitting light over long distances with minimal loss. A metal diaphragm-based omnidirectional fiber-optic acoustic sensor with high sensitivity has been developed in this work. The acousto-optic transducer of the sensor is a single-wavelength extrinsic Fabry–Pérot interferometer (EFPI) that is highly sensitive to the displacement of the diaphragm's. Rayleigh scattering -based distributed acoustic sensing (DAS) systems use fiber optic cables to provide distributed strain sensing. This signal can then be measured by an instrument or interpreted by a user. In essence, a sensor reacts to a physical, chemical, or biological condition. In the realm of biometric recognition, fingerprint recognition has gained success with its convenient operation and fast identif ication speed. Under identical sound pressure conditions, the proposed EFPI sensor achieves a peak-to-peak output voltage of 849.
