  • Time multiplexed fiber optic sensor
    Patent number: 5004911
    Abstract: An optical sensor system utilizes time multiplexing of two optical signals developed from a common light source. Relative amplitudes of the two optical signals are varied as a function of a measured parameter, time multiplexed, and coupled to a common optical transmission path. At the receiving end of the optical transmission path the two optical signals are converted to electrical signals by the same detector, thus eliminating sensitivity to source gain, interconnect fiber loss, and detector gain as sources of calibration error.
