Paper Abstract

We perform a rigorous, diffraction-based analysis to find an analytical expression for the point spread function of the multiple Bracewell interferometric (in-line, even, multi-aperture) configuration, in a single and double embodiment, proposed for extra-solar planet detection. The number of apertures, total length of the linear interferometer array, and the diameter of individual aperture control the shape of this function. The square of the Bessel function modulates the square of the multiple-beam interference term, attenuating it rapidly for off-axis values of the angle.
