High acquisition rate infrared spectrometers for plume measurement

Résumé

For a few years, Onera has developed static Fourier transform spectrometers. These spectrometers are napshot and benefit from a high étendue, thus making them well suited for measuring fast moving scenes, such as rocket plumes. In particular, Onera has developed two cryogenic infrared instruments, Mistere and Microspoc, which can measure spectra at a high repetition rate (few hundred of Hertz), on a wide spectral range ([2.9μm ; 9.6μm] and [1.5μm ; 5μm]), and with a moderate spectral resolution (15cm-1 and 30cm-1). The design of these spectrometers will be presented, as well as examples of experimental results.
