“…Nine simulation cases are presented in Figure 6, as an illustration of the effect of the distance of the star from the origin of the primed coordinate system. They are all interference patterns, calculated according to Equation (32). First the figure organization is explained.…”

“…Furthermore, the shearing interferometry incorporates a temporal element under control of an Earth user that allows the development of a causal relationship in the detected pattern when the planet is within the instrument field of view. Originally, the theoretical analysis was developed by substantiating that the rotationally shearing interferometer (RSI) may detect an invisible distant planet orbiting a bright, large star [27][28][29][30][31][32][33][34][35]. The traditional Mach-Zehnder interferometer, that requires a reference surface for its functioning, is transformed into an RSI when a rotated Dove prism is inserted in one of its arms, as illustrated in Figure 2.…”

The astronomers and the general population are fascinated with the problem of exoplanet detection. By far the largest number of detected planets are the so-called Super Earths, relatively cold planets orbiting a large, red giant star, with diameters up to 1 AU, most of them at about one hundred light-year distance from us. A rotational shearing interferometer (RSI) was proposed for exoplanet detection. Here the detection capabilities of the RSI are expanded to include the case when the interferometer is not precisely aligned on the star. The theoretical analysis is applied to the case of a Super Earth with the red giant star, displaced from the origin to the Mercury, Earth, and the Martian orbit. For errors in alignment up to the Mercury orbit, the red giant star generates a slanted radiance pattern that may be eliminated using information processing. For larger distances, analysis in the Fourier domain is feasible.
