Optical Path Analysis of the Optical Fiber Bundle Hydrogen Sensor

Abstract:

The present work investigates reflectivity and optimal reflective distance of optical fiber hydrogen sensor in over 0～4000um range. The approximate equality of reflective distance in two optical paths increases signal to noise ratio for optical hydrogen sensor, the fabrication of optical path could eliminate the internal noise and external interferences, and provides higher stability for hydrogen sensor. Through a series of simulation experiments it was found that different reflective distances determine the sensitivity and amplitude response of hydrogen sensor. When the reflective distance was about 1mm in optical path, the sensitivity of optical hydrogen sensor could reach the peak value.
