Our instrument is a
Connes type Michelson interferometer.
It is a stepping mode spectrometer. This home-made instrument is dedicated to the implementation of new experimental methods. Spectral and time resolution are respectively 2.5 10-3 cm-1 and 2 ns at best. Selective detection techniques have also been implemented. Present research is devoted to the search of higher sensitivities by heterodyne detection. Related www pages of our group :  Fourier
