Abstract :
It is shown that a frequency modulated laser diode source can be used to combine frequency division multiplexing and time domain addressing techniques to increase the number of interferometric sensors in a multiplexed fibre optic system. Demultiplexing is carried out in both the frequency and time domains to generate independent heterodyne carriers for different interferometers
