title: Multichannel-fiber ringdown sensor based on time-division multiplexing.
abstract: A multichannel-fiber ringdown sensor based on the principle of time-division multiplexing is described. The purpose of multiplexing is to obtain the information of one or more fiber ringdown sensor heads simultaneously under the premise of cost neutrality. To illustrate the principle, we study the typical dual-channel fiber ringdown force sensor in our experiment. It shows that the pressures at two different points can be measured simultaneously. In addition, we find by measurement that our sensors have good linear responses above the response threshold of the applied force.
