Abstract:
    The invention relates to an identification signal detecting device and method, where the detecting device comprises: photoelectric converter for converting optical signal modulation wave into electric signal modulation wave; signal divider connected with the photoelectric converter to divide the electric signal modulation wave according to the wavelength or frequency of the identification signal loaded on the electric signal modulation wave; plural spectrum analyzers with different frequency band ranges, separately connected with the signal divider to make spectrum analysis on the divided electric signal modulation waves. Thus, it reduces spectrum analysis calculation quantity, shortens spectrum analysis calculation time by times, improves analysis result accuracy and therefore raises operating efficiency of the identification signal detecting system.
