Abstract
To remain Doppler-limited, the extension of the working range of the High Information Fourier Spectrometer to the infrared has to be accompanied by an increase of the resolution. The preliminary teats, reported here last June, done on the double passing of the path difference were not satisfactory enough and led us to make a quadruple path system. The non-apodized apparatus function has consequently a halfwidth of about 20 MHz. Description of the system and preliminary results will be given.
