Paper Abstract

We report experimental results from the Phase Knife Coronagaph which validate our previous theoretical and numerical simulations, prove the physical principle of it and set realistic limitations to the nulling properties of the coronagraph. The optical set-up, phase knives manufacturing technique and different aspects of the instrumental limitations are given. The first results attain easily a 3000 nulling effect obtained both on single and double simulated stars. Optical and mechanical stabilities are discussed and future steps to be carried out are outlined.
