Various methods of synthesis imaging with nulling interferometers have been proposed. These methods are based on the principle that brightness distribution in the sky is reconstructed through Fourier transformation of complex visibility. Here, we present a novel imaging interferometry technique for direct detection of exoplanets. According to this new method, only two measurements of the complex visibility are required for reconstruction of the sky. Spectra of the planets can be also estimated from information on their positions and the complex visibilities, its number corresponding to the number of the planets. This paper shows the theory of this new imaging method.
