Procedure of image reconstruction. Panel a shows the planet position for this simulation. The planet is positioned at 1 AU in parallel to the x-axis, where (x, y) is the coordinate system of the object plane in the unit of AU. The planetary system at 10 pc consists of only one Earth-radius planet with an effective temperature of 285 K (without its host star). Panel b shows the directions of the imaging baseline for the two reconstructed 1D images (panels c and d). Panel e shows a 2D image converted from the set of the 1D images. The vertical axis of panels c and d and the color bar of panel e represent the number of photoelectrons. The parameters of the telescope and instrument are compiled in Table 2.
