Abstract
Apparatus for optically multiplexing the signals of several optical sensors when those sensors are of the type which utilize a single light input optical fiber for each sensor to send light to the sensor from a central monitoring station and a single signal output optical fiber for each sensor to communicate the light output of the sensor back to a single receiver in a central monitoring station. There is provided means which will sequentially introduce a predetermined amount of light flux into the sensors and thereby produce signal outputs from those sensors indicative of the magnitude of the quantities being measured. There is also provided means to communicate those outputs to a single common optical receiver.
