Abstract
Modern astronomy is dominated by the development from ground and from space of large imaging survey programs at all wavelengths. They generate huge databases which call for low-resolution, high-sensitivy follow-up spectroscopy, in particular by integral field spectroscopy. Hence, the niches for FTS application are reduced. However, some properties of FTS remain of special interest for astronomy, as the large spectral coverage with a single detector which is used for several projects in the far-IR and sub-mm domain (ASTRO-F, HERSCHEL), and the imaging mode obtained by the coupling of a step-by-step FTS with a 2D-detector (BEAR, SPIOMM, LLNL/IFTS). The planets remain also a target for FTS in space and from ground (Cassini/CIRS, Mars Express/PFS, CFHT/FTS). Some recent results are presented.
