Abstract

An infrared, rotating, rotationally-shearing interferometer is proposed for the detection of a planet around a nearby star. The fringe visibility pattern is shown to depend only on the planet parameters. The expression for the interferometric pattern generated by a star and its faint companion detected by a rotationally-shearing interferometer shows that the planet may be detected only if the aperture rotates. Additionally, we show that the shearing interferometer does not suppress the star light--the interferometric pattern is proportional to the star intensity.
