摘要：
We derive the analytical expression for the star-planet incidence detected with a (variable angle) rotationally-shearing interferometer, with the absence of star-related quantities. The rotationally-shearing interferometer detects only the tilted wave front incident from a planet. The partial polarization of two rotated beams diminishes the signal amplitude by a factor proportional to the cosine-square of the shearing angle. The polarization considerations favor the small-angle implementation of the rotationally-shearing interferometer. (C) 1999 Elsevier Science B.V. All rights reserved.
