Abstract

We are studying the feasibility of using a rotational shearing interferometer to detect a planet in a nearby solar system. In this paper, we describe the status of our work. We built a rotationally shearing interferometer and demonstrated that a simulated star indeed produces a field without fringes. The faint simulated planet provokes appearance of faint fringes. Their density and slope may be changed upon changing the shear angle when the planet is present.
