An IFPI Temperature Sensor Fabricated in an Unstriped Optical Fiber with Self-Strain-Compensation Function

Figure 9

(a) Main IFPI sensor waveform shifts to the longer wavelength range. (b) Test result before compensation in blue line. After compensation, by linearly subtracting the strain information, the result of spectrum matches the temperature calibration from experiment 1.
