Research on Gas Chamber of Reflective Optical Fiber Hydrogen Sensor

Article Preview

Abstract:

Gas chamber is one of the most important problems of the optical fiber hydrogen sensor, which directly affects the quality of the sensor sensitivity. For reflective optical fiber hydrogen sensor, the gas chamber was researched in this paper. First, the gas chamber structure and optical loss for reflective optical fiber hydrogen sensor was analyzed. Then design requirements to the gas chamber were discussed, including isolation the gas flow of reference part and measurement part, distance of the probe and the reflector, the tilt angle of the reflector. By using the gas chamber in the reflective optical fiber hydrogen sensor, it illustrates better effect.
