Abstract

A tandem-vortex coronagraph can in theory enable high-contrast imaging behind a classical on-axis telescope. Here we point out that a tandem-vortex coronagraph configuration can also directly enable the measurement of the phases of focal-plane speckles, thereby allowing for their suppression in the resultant high-contrast image.

Fig. 2

Common-path interferometer layout (starting in the second Lyot plane of the tandem-vortex coronagraph of Fig. 1) and resultant focal-plane crosscut, the latter showing the relative widths of the various PSFs, including the wide reference beam (ref, in red), the speckles (s and s * , in gray), the planet (p, in blue), and the residual starlight ( ( d / D ) 4 , in blue). The beam in the second Lyot plane is shown hitting reflective optics, to indicate a possible implementation, using a small central phase-shifting mirror.
