Paper Abstract

We proposed a dual-channel imaging polarimetry system .It will be integrated in our coronagraph that was proposed for direct imaging of Jupiter-like planets, providing an extra high contrast for the extra-solar planet imaging. This system uses a Wollaston prism, which separates the unpolarized starlight and the polarized planet light. The two point images in perpendicular polarizations are imaged simultaneously. We describe the design of the imaging polarimetry system, and discuss the data reduction algorithm. In particular, the correction of distortion of the two channels is discussed in detail.
