Abstract. Three terms of the eikonal distribution expansion in the aperture of a symmetric two-mirror imaging system in powers of a source transverse displacement from one of the foci have been obtained. The terms of the expansion are expressed through the mapping function and its derivative. The accuracy of the derived formula has been checked for the aplanatic two-mirror system.
