1. An optical electronic multiplexing reflection sensor system comprisinga plurality of fiber optic cable buses;

  • a plurality of groups of strain and temperature sensors, each of said groups being connected in series in a corresponding one of said buses, a unique address being provided each sensor function by wavelength selection in each of said buses;

    demultiplexing means coupled to said buses for demultiplexing the individual wavelengths, said demultiplexing means comprising a laser source coupled to each of said buses and plurality of monochromators each coupled to a corresponding one of said buses and to said laser source, each of said monochromators having control means connected thereto for controlling the operation of the monochromator to which it is connected;

    detecting means for detecting analog data from a discrete sensor function;

    digitizing means for digitizing detected analog data; and

    backbone network means for distributing and processing digitized data.
