摘要：

The light from extrasolar planets is expected to be partially polarized. The image of an extrasolar planet can be obtained from its polarized light with a polarization interferometric nulling coronagraph, where a four-quadrant polarization mask is used. A two-channel stellar coronagraph allows the detection of extrasolar planets by subtracting scattered light from its host star. Laboratory experiments confirm that faint extrasolar planets can be imaged with the two-channel polarization nulling stellar coronagraph.
