| Abstract: | Based on the characteristic of spectrum absorption of CO,a set of optical fiber detection system with reference gas cell is designed,which has reference channel and is for on-line and real-time detection.Two wavelength differential absorption measurement is used to eliminate the interference owing to various disturbances,such as light power,optical fiber,sensor head changing,thus the sensitivity is improved.Some experimental results are presented.Results show the sensor has many characteristics such as simp... |
