Abstract

The Michelson interferometer flown on Nimbus III in April 1969 has obtained infrared emission spectra of the earth and its atmosphere within 400 cm(-1) and 2000 cm(-1) (5 micro and 25 micro). Spectra of good quality have been recorded with a spectral resolution corresponding to 5 cm(-1). This paper discusses the design of the instrument including the optical layout, the phase locked loop operation of the Michelson motor, and the functioning of the reference interferometer. The methods of data reduction and in-flight calibration are demonstrated on sample spectra recorded while in orbit around the earth.

摘要

1969年4月搭载在“雨云三号”卫星上的迈克尔逊干涉仪，获得了地球及其大气层在400厘米⁻¹至2000厘米⁻¹（5微米至25微米）范围内的红外发射光谱。已记录到质量良好的光谱，其光谱分辨率相当于5厘米⁻¹。本文讨论了该仪器的设计，包括光学布局、迈克尔逊电机的锁相环操作以及参考干涉仪的功能。在环绕地球轨道运行时记录的样本光谱上展示了数据处理和飞行中校准的方法。
