		| Abstract: | 
		Experiments have been conducted on a two-channel nulling stellar coronagraph. Our nulling stellar coronagraph is based on polarization interferometry and a differential polarimetric method enables detection of polarized light from extrasolar planets, by removing unpolarized light from the host star. The laboratory experimental results are shown. |
