Design and Analysis of FKSI Nulling Interferometry TestbedThe Fourier Kelvin Stellar Interferometer is a space borne mission whose purpose is to validate the existence of previously detected Extra Solar Giant Planets (EGP's) and determine the age and primary atmospheric constituents of these EGP's. It consists of 2 collecting telescopes followed by a Mach Zehnder interferometer working in a wavelength range of 3-8 microns. To support this concept, a testbed is being built at NASA Goddard Space Flight Center to demonstrate feasibility of achieving the required nulling ratio (10e-4) across the waveband. This paper describes the design and performance analysis of the testbed. Considerations such as polarization, pupil overlap, and optical path length control are discussed.
