The Far-Infrared Surveyor (FIS) is one of the two focal plane instruments of ASTRO-F which is a Japanese infrared astronomical satellite planned to launch in early 2004. The FISis designed primarily to perform an all-sky survey in 4 photometric bands at wavelength of 50 -200 μm . The sensitivity of the FIS is several ten times higher than IRAS (Infrared AstronomicalSatellite) because of the improvement on the detector performance based on the recent device technology. The FIS is expected to provide a new generation all-sky catalog of infrared sources, whichcould become a standard database in many fields of astrophysics. The FIS also has spectroscopiccapability which is realized by a Fourier transform spectrometer. The spectrometer covers 50 - 200cm-1 in wavenumber with 0.2 cm-1 spectral resolution. The spectrometer is quite a powerful toolto reveal the physical properties of the objects such as new objects detected by the all-sky surveyor known interesting sources.
