POLYCHROMATIC LABORATORY TEST BENCH FOR DARWIN / TPF : FIRST RESULTS

The validation of nulling interferometry principle is a crucial step on the way to space missions DARWIN/TPF concepts that aim at detecting and analysing extrasolar planets. In this context, different laboratory techniques of recombination are currently under development. We present in this poster the new polychromatic test bench at IAS and its very first results in the 2 to 2.5 µm band.
