Abstract

We are developing a bolometric astronomical interferometer in mm and submm wave bands by applying Martin-Puplett type Fourier transform spectrometer to aperture synthesis technique. Since the spectroscopically resolved intensity distribution of four Stokes parameters are measurable by this instrument, we refer this to multi-components Fourier transform interferometer abbreviated as MuFT. Fundamentals of the MuFT with results of laboratory experiments and current status of astronomical observations with MuFT are summarized.
