Paper Abstract

We describe preliminary experimental results on the identification of a planet in a simulated solar system using a rotationally shearing interferometer. We use two lasers, placed at approximately 90 degrees with respect to each other, each with a beam expander and a common collimator lens, to simulate the wave fronts from the star and offaxis planet. We confirm the theoretical prediction that the off-axis planet produces fringes whose density increases with the angle of rotation of the Dove prism in the rotational shearing interferometer. The star generates a uniform wave front that is invariant to the angle of rotation of the Dove prism, enhancing the variable fringes arising from tilted off-axis planet wave front. The inclination and density of planet fringes are under control of the experimentalist.
