In the study of extended sources such as star forming regions, galactic planetary nebulae or comets wide field integral-field spectroscopy at high spectral resolution in the infrared, would be the ideal tool. It is shown that an imaging FTS (IFTS) is the only instrument which can combine a wide field, up to ~10', with a spectral resolution ≥105. At Dome C, in the 2 to 25 μm region, as instrument of a 3-m class telescope, a wide-field IFTS would have no equivalent in space and on ground. It can take full advantage of all the astronomical properties of this site, in particular the lowest thermal background emission conditions on Earth. A program to simulate the expected performances has been developed. At the highest resolution the best sensitivity implies the use of narrow-band filters on the emission lines of interest.
