| 中文摘要 | 研制了一套基于数字反馈稳频的便携式瓦斯浓度遥测装置,采用电流和温度双重反馈稳频的策略抑制了激光器波长的长期漂移,同时也保证了光功率的长期稳定性。实验结果表明,9h内激光器波长的长期漂移小于1.2 pm,光功率保持稳定,保证了瓦斯浓度的长期连续稳定的测量;不同距离下浓度测量值重复性较好,浓度波动小于5%,满足实际环境中(如天然气管道泄漏、煤矿等)瓦斯浓度测量需求。 |
| 英文摘要 | A portable methane remote sensor based on digital feedback frequency stabilization is developed. Current and temperature dual-feedback strategy suppresses the laser's long-term wavelength drift; meanwhile it ensures the long-term stability of optical power. Experimental results show that the wavelength drift is less than 1.2 pm in 9 h, and the optical power also remains stable, which ensures the long-term continuous measurement stability of the concentration. Repeatability of concentration measurement value is stable in different detection distances, with a 5% fluctuation. Experimental results indicate that the instrument can be used in practical environment, such as natural gas tube leakage and coal mine. |
