  • Neural network demodulation for an optical sensor
    Patent number: 7603004
    Abstract: Methods and systems of neural network demodulation for an optical sensor. An optical sensor may be coupled to a structure and be capable of reflecting a reflected optical signal. A wavelength of the reflected optical signal may be spread based on a strain being applied to the structure. A replication device may receive the reflected optical signal from the optical sensor and produce a plurality of optical signals. A filter may be coupled to the replication device to receive an optical signal from the plurality of optical signals and filter the received optical signal. A detector may receive the filtered optical signal and provide a voltage output proportional to an amount of the filtered optical signal received. A neural network may receive the voltage output and determine the strain on the structure.
