Abstract

We use the modulation transfer function (MTF) to evaluate the performance of several multi-aperture interferometric configurations for the detection of a faint planet in the vicinity of its bright star. We design non-redundant interferometric layouts that provide satisfactory coverage of the spatial frequencies of interest. We propose a design incorporating a rotating, rotationally shearing interferometer in a gravity-free environment. The side peak of its MTF may be centered on the spatial frequency associated with likely planet coordinates, resulting in the planet signal enhancement and isolation.
