摘要：

We present a multiplexed quasi-static strain sensor system with sub-nano resolution based on the transient response of fiber Fabry-Perot interferometers. A 3-channel strain measurement with resolution better than 0.2 nc/root Hz in frequency band from 0.1 Hz to 100 Hz is realized in the demonstrational experiments.
