| Abstract: | The refractive index and temperature sensing principle of the fiber Bragg grating(FBG) biosensor was analyzed theoretically.A single-end etched FBG was designed and fabricated for simultaneous measurement refractive index and temperature.Temperature compensation scheme was proposed by using numerical calculation eliminate temperature changes to the influence of biosensor.Experiment results showed that the variation of Bragg wavelength increased as the yeast training time increased,in 0~10 h the growth of ye... |
