摘要

在美国国家科学基金会大气科学部的资助下，研制了一种用于垂直平流层臭氧遥感的外差光谱仪。在10 /spl mu/m区域，利用微波边带CO/sub - 2/激光光谱仪对NH/sub - 3/的吸收光谱进行了分析，并在选定的跃迁上成功地获得了0.0002 cm/sup -1/的分辨率。此外，还报道了调制器的可调性和性能。调制器可以在8-18 GHz之间调谐，最小输入功率为18瓦。

Electro-optic modulator for remote sensing in mid-infrared ozone detection

Under the program sponsored by NSF- Atmospheric Science division, a heterodyne spectrometer for remote sensing of vertical stratospheric ozone is being developed. In the 10 /spl mu/m region, a microwave-sideband CO/sub 2/ laser spectrometer has been used to find absorption spectra of NH/sub 3/, a resolution of .0002 cm/sup -1/ has been successfully demonstrated on selected transitions. In addition, tunability and performance of the modulator has been reported. The modulator can be tuned from 8-18 GHz with minimum input power of 18 watts.
