ABSTRACT:
An infrared interferometer, which includes a moving mirror, a fixed mirror, a beam splitter for delivering an interference light and a sensor for sensing the interference light, for observation of atmospheric spectra is equipped with a cloud observation arrangement for determining the cloud coverage ratio and the altitude of the top surface of a cloud, comprising a reflecting mirror for extracting a part of the interference light, a narrow-band-pass filter for A and B bands of oxygen molecules and a sensing element, the cloud observation arrangement enabling simultaneous observation with the atmospheric spectra observation to eliminate harmful influence of the cloud therefrom.
