Astronomical measurements at mid- and far-infrared wavelengths can be made by using aircraft or balloons to carry telescopes above the strongly absorbing lower atmosphere. To measure the atmospheric background radiation present at these altitudes, a Michelson interferometer has been built and flown to a height of 38 km on a balloon. This paper describes the instrument and the methods of data reduction and calibration, and presents initial spectra in the range 100-1000 cm(-1) (10-100 micro) obtained to a mean resolution of 34 cm(-1) during flight.
通过使用飞机或气球将望远镜携带到强烈吸收的低层大气之上，可以进行中红外和远红外波长的天文测量。为了测量这些高度存在的大气背景辐射，已经制造了一台迈克尔逊干涉仪，并通过气球将其升至38公里的高度。本文描述了该仪器以及数据处理和校准方法，并展示了在飞行期间获得的100 - 1000厘米⁻¹（10 - 100微米）范围内的初始光谱，平均分辨率为34厘米⁻¹。
