Abstract: An optical electronic multiplexing reflection sensor system for a plurality of Bragg sensors connected in series spaced relation in a plurality of single mode fiber optic cable buses. In each of the buses a unique address is provided each sensor function by wavelength selection. Each of a plurality of monochromators is coupled to a corresponding one of the buses and has a control connected to it for controlling the operation of the monochromator. A tunable laser source is coupled to each of the buses. A wavelength sweep generator is coupled to the laser source and provides outputs to the controls of the monochromators. Each of a plurality of photodetector receivers receives the output of a corresponding one of the monochromators and each has an output providing output signals indicating individual wavelengths of the Bragg sensors coupled to it. Each if a plurality of analog to digital converters is connected to the output of a corresponding one of the photodetector receivers. A backbone network connected to the analog to digital converters distributes and processes digitized data.
