Paper Abstract

The light from exoplanets is expected to be partially polalized and the image intensity becomes different with the polarization direction. Based on this expectation we have reported the laboratory experiment of two-channel nulling stellar coronagraph for direct imaging of exoplanets, where a differential imaging with respect to mutually orthogonally polarized light is conducted. We show that this differential technique is also useful for obtaining objective spectra of exoplanets. Several experimental results on the differential objective spectrometer are reported.
