Paper Abstract

We develop some conditions to detect extra-solar planets with rotational shearing interferometer. We consider that the star is not on the interferometer axis. In addition, we include an arbitrary optical path difference between the interferometer arms. Previously, we showed that the light from the star may be cancelled out when the OPD is λ/2. We obtain analytic expressions for these conditions. We simulate several incidance distributions of the star-planet system. It is of utter most importance to align the interferometer axis with the host star, to the precision of 5 μrad.
