“…New highly sensitive technologies able to perform spectroscopy in the millimetre / sub-mm regime are being developed (such as spectroscopy on a chip with bolometric detectors 15,16 ). They might well be technologies that will be used for a distant space mission, but due to their present lack of maturity, the obvious choice for a broad spectral range spectrometer is a FTS, which has also the benefit for its spectral resolution and frequency coverage to be optimised even during the flight if necessary.…”

The BISOU (Balloon Interferometer for Spectral Observations of the Universe) project studies the viability and prospects of a balloon-borne spectrometer, pathfinder of a future space mission dedicated to the measurements of the CMB spectral distortions, while consolidating the instrumental concept and improving the readiness of some of its key sub-systems. A balloon concept based on a Fourier Transform Spectrometer, covering a spectral range from about 90 GHz to 2 THz, adapted from previous mission proposals such as PIXIE and FOSSIL, is being studied and modelled. Taking into account the requirements and conditions of balloon flights (i.e. residual atmosphere, observation strategy for instance), we present here the instrument concept together with the results
