FIRI (Far Infrared Interferometer) is a concept for a spatial and spectral interferometer with an operating
wavelength range 25-300 μm and sub-arcsecond angular resolution, and is based in the combination of two well-known
techniques, Stellar Interferometry and Fourier Transform Spectroscopy to achieve high spectral and spatial
resolution in the Far Infrared. The resulting technique is called Double Fourier Spatio-Spectral Interferometry
(Mariotti and Ridgway 1988). With increased spatial and spectral resolution a number of interesting science cases
such as the formation and evolution of AGN and the characterization of gas, ice and dust in disks undergoing
planetary formation, among others, can be investigated. Here the current status of the design of the FIRI system
via an instrument simulator is presented, as well as the results of a test-bed implementation.
