A Dual 3-Element Nulling Interferometer for TPF
We present an interferometer that provides a null at the star and a direct measurement of both visibility amplitude and phase of the planets.

Polarization compensating protective coatings for TPF-Coronagraph optics to control contrast degrading cross polarization leakage
We describe here the design approaches and performance analysis of the OTA in the wavelength band of interest. Coronagraph performance at 600nm wavelength based on a particular coating and occulting focal plane mask is also presented.

Understanding other worlds: NASA's missions to find and characterize extrasolar planetary systems
About 150 extrasolar planets, mostly much more massive the Earth, are now known from ground-based observations. Earth-mass planets are very hard, if not impossible, to detect from the ground. The study of planets like our own Earth, orbiting in a 'habitable zone' around their parent stars, will require a new generation of space-based instruments.

TPF Planet Detection Testbed: demonstrating deep, stable nulling and planet detection
The design of a testbed being built at the Jet Propulsion Laboratory is described. Simulatiung a dual chopped Bracewell interferometer, the testbed comprises a four beam star and planet source and nulling beam combiner. Since achieving a stable null is of great concern the testbed has many control systems designed to achieve stability of alignment and optical path difference over long periods of time. Comparisons between the testbed and the flight system are drawn and key performance parameters are discussed. The interaction between designs for phaseplate systems that achromatically invert the electric field of one of each pair of the incoming beams to achieve the null and the choice of fringe tracking schemes is also discussed.
