摘要：

A detection scheme of coherence multiplexed sensor signals by using an optical loop incorporating a frequency shifter is proposed and demonstrated. The sensor signals are frequency-multiplexed, and consequently, the numbers of the receiving interferometers and the photodetectors can be reduced.
