Research status and development of optical fiber hydrogen sensor
Due to the flammable and explosive chemical properties of hydrogen,it is easy to cause explosion accidents in all aspects of preparation,transportation and usage. Therefore,it is of great significance to use efficient and accurate hydrogen sensors to monitor hydrogen in time and accurately to reduce the safety problems caused by hydrogen. This thesis mainly introduces the structural characteristics,working principle,characteristics and research status of four kinds of optical fiber hydrogen sensors which are being studied at this stage. Based on this, the development status,advantages and disadvantages are briefly analyzed. Finally,the future research direction of optical fiber hydrogen sensor is prospected.
