| 摘 要： | 基于散射光的被动差分吸收(DOAS)技术利用气体的特性吸收谱线可实现对不同大气污染气体的定量测量，介绍了一种基于成像光谱仪的光学遥感系统，该系统运用被动DOAS原理实现了对大气污染气体的二维成像测量，并报道了该系统对实验室样品池一维测量与城市道路上方NO2组分的成像测量实验. 基于成像光谱仪的被动DOAS系统利用太阳散射光可获取垂直方向一维的光谱信息，结合扫描装置，便可实现对污染气体的二维成像解析.

| Abstract: | The technique of passive differential optical absorption spectroscopy (DOAS) is based on fingerprint absorption of probed gas species, which enables simultaneous monitoring of a variety of pollutants found in the atmosphere using scattering light as light source. We describe an optical remote-sensing instrument which is based on imaging spectrometer that permits spatially resolved mapping of atmospheric trace gases by passive DOAS method. The applications of one spatial dimensional measurement of gas cell and imaging of the nitrogen dioxide over city main road were also reported in this paper. With scattered sunlight as the light source, the system based on imaging spectrometer simultaneously acquiring spectral information in one spatial dimension, the second spatial dimension is scanned by a moving mirror. |
