Abstract
An infrared rotating rotationally-shearing interferometer is proposed for the detection of a planet around a nearby star. The fringe visibil ity pattern is shown to depend only on the planet parameters. The expr ession for the interferometric pattern generated by a star and its fai nt companion detected by a rotationally-shearing interferometer shows that the planet can be detected only if the aperture rotates. Addition ally, we show that the shearing interferometer does not suppress the s tar light. The interferometric pattern is proportional to the star int ensity.
