摘要:Based on laser absorption spectroscopy and optical fibre sensing technology, this study proposed an optical fibre oxygen detection sensor. Moreover, using a vertical cavity surface emitting laser (VCSEL) with a wave length of 763 nm as the light source, a Herriot principle-based optical fibre long-optical path detection air chamber was developed, which resulted in the stable, long-term operation of the system. This oxygen detection system covered the full possible measuring range of 0-100% with a detection error of less than 0.15%. Moreover, it realised multi-channel detection at maximum of 3 km. The results showed that the oxygen sensor showed good performance and stability and was applicable to on-line detection in an environment containing multiple- and long-distance targets.
