Opto-electronic method and system for remote detection of physical magnitudes |
| abstract |
The optoelectronic method and system provides for remote detection of physical magnitudes by multiplexing and demultiplexing signals from a plurality of sensors. The system utilizes a single source of incoherent light which illuminates via optical fibers a plurality of sensors associated with encoding devices. Periodic modulation on the light transmitted by each sensor is accomplished at a frequency which is characteristic of the sensor in question. Demultiplexing is provided for demodulating the signals from the various sensors by a Fourier transform, and for identifying each signal by its characteristic modulation frequency. |
