Abstract
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.
摘要
利用光学涡旋日冕仪，演示了一种利用单个元件探测器从极未解析的光源中提取空间信息的方法。该方法的应用范围可以从天文学扩展到显微镜学。例如，可以揭示未解析的非相干点源集合的质心和角扩展。
