Image of a star system seen through a Michelson interferometer d / D = 1 equipped with the multi-axial design of order n = 7. The system consists of a star and a 10⁶ fainter planet. The light from the star is shown in yellow and the one from the planet in blue. The image intensity I has been enhanced by a I^0.25 filter to see the very low levels (here: the star). The effect of the device is to push away the light from the star, while that of the planet fits in the space left empty. To illustrate the achromatic effect, the observation is simulated for a wavelength detuned by 10% compared to the central wavelength λ₀.
