The viability and economy of optical fibre sensors is greatly improved by multiplexing, the method by which many individual passive heads can be interrogated by a common opto-electronics terminal. For space applications, multiplexing offers the added attraction of greatly reduced weight, as the fibre cable network and passive sensor units will generally be much lighter than their electrical counterparts and there is no need for heavy electromagnetic screening materials. The ultimate form of multiplexing, and the maximum weight saving is achieved when the sensor consists of a single length of fibre cable and where the terminal unit can monitor and resolve the variation of a physical parameter, as a continuous function along the length of the fibre. Such a sensor is called a distributed sensing system.
