摘要
论述了气体的吸收光谱与区域有害气体光谱探测技术的基本原理,探讨了差分吸收光谱技术,提出了区域远程毒气快速探测的实现方法,介绍了宽光谱光束探测痕量气体入侵、多组光谱仪测试,利用差分吸收光谱法研究出毒气报警系统,并对仪器的发展趋势进行了展望。
The basic theory of gas absorption spectroscopy and long - distance nocuous gas exploration technology were dissertated. The technology of differential optical absorption spectroscopy （DOAS） was discussed. The actualization method of the nocuous gas detection in the long - distance area was put forward. The trace intrusion gases detection method with wide spectrum light beam, a series of optical apparatus and DOAS computing were introduced. The potential technologies and instrument in the future were prospected.
