利用干涉成像光谱技术被动探测上层大气风场所使用的光源主要是氧禁戒线极光。讨论了禁戒跃迁出现较强谱线需要的两个条件
对满足上述条件的上层大气中的原子氧(OⅠ)和离子氧(OⅡ)的可见光波段禁戒线进行了详细的计算
并对应指出产生这些O(Ⅰ
Ⅱ)禁戒线的光化学反应。得出的结论是被动探测上层大气风场所用极光源可以使用所指认的10条O(Ⅰ
Ⅱ)禁戒线和允许线:557.7nm
630.0/636.4/639.3 nm
672.8nm
732.2/733.2nm
777.7/777.6/777.4nm
比加拿大的风成像光谱干涉仪(WINDII)使用的极光谱线增添了5条:639.3nm
672.8nm
777.7/777.6/777.4nm
扩展了成像光谱干涉仪的波段范围。
To detect wind field in the upper atmosphere passive methods was used with imaging interferometer technique the main source is O(Ⅰ
Ⅱ) forbidden aurora. For stronger forbidden transition line
two necessary conditions of theoretical calculation are metastable and enough small electron density. O (Ⅰ
Ⅱ) satisfies the conditions and its forbidden lines are indicated. Then the corresponding photochemical reaction of O (Ⅰ
Ⅱ) forbidden aurora was investigated. The conclusion is that 10 forbidden (allowed) lines (557.7 nm
630.0/636.4/639.3 nm
672.8 nm
732.2/733.2 nm
777.7/777.6/777.4 nm) can be used to detect upper atmospheric wind field
5 lines (639.3 nm
672.8 nm
777.7/777.6/777.4 nm) increased comparing to WINDII
the visible wavelengths aurora is enlarged for imaging interferometer.
