Abstract:
1. A sensing method including the following steps: (a) providing a stabilizing device, an optical fiber sensing device, an optical device, a signal processing device, and a connected pipe; (b) providing an optical fiber, two heat shrinking tubes, a cable in said optical fiber sensing device, and at least one measuring device is made in at least one of the plurality of measuring segments in said optical fiber; wherein the two ends of said cable and the ends of said optical fiber are joined by said heat shrinking tubes;  said measuring segments are located between said heat shrinking tubes; and (c) one end of said cable is linked to said stabilizing device, and a securing end is composed opposite to said stabilizing device; connecting said optical device to one end of said optical fiber sensing device;  wherein said optical device emits an optical signal into said optical fiber, and receives the reflected signal from said measuring segment; (d) coupling said signal processing device with said optical device; (e) connecting one end of said stabilizing device to the other end of said optical fiber sensing device and floating said stabilizing device in a liquid contained in the connected pipe, to provide said measuring segment a pre-determined tensile strength and maintain said measuring segment in a first status; (f) applying a force to said measuring segment to make said measuring segment change to the second status; said reflected signal produces a signal change during said measuring segment changes to second status; and (g) said signal processing device converts said signal change into physical parameters.
