In a coronagraph obtained by the Lyot principle, the energy of boundary diffraction waves is concentrated by the field lens into a circular zone around the image of boundary of the objective lens.
In this paper the effect of boundary diffraction waves is discussed analytically.
It is deduced that, when the point source is on the optical axis, the width of the concentrated zone is of the order of the diameter of the airy disk formed by the aperture of occulting disk.
