ABSTRACT:
In an optical instrumentation system, sensor units are solely constructed optically and each sensor unit comprises a subcarrier generating section for causing periodic changes in the light intensity of light wave from a light source corresponding to the wavelength sweep of the light source to generate a subcarrier, and a sensor section for modulating the subcarrier by detected information, and at the receiving end of the system a demultiplexing section is provided for demultiplexing detected information by selecting the subcarrier.
