Abstract
En 中文
A means to extract spatial information from an extremely unresolved source of light using a single element detector is demonstrated by use of an optical vortex coronagraph. Applications may range from astronomy to microscopy. For example, the centroid and angular extent of an unresolved collection of incoherent point sources is revealed.
