The SPICA-Safari instrument, currently being proposed as an ESA M5 mission, requires line sensitivities of order 10-19 W/m2 (5σ-1hr) between 34-230 μm. In this paper we will give an overview of the mission and instrument. In particular we will present a cryogenic post-dispersed Martin-Puplett Interferometer scheme, utilizing extremely sensitive TES detector arrays, to implement a high-resolution mode (R ≈ 103-104), offering unprecedented spectroscopic observing capabilities in the far-IR.
