Abstract
Spatial-mode demultiplexing (SPADE) scheme has been successfully used in quantum Cramer-Rao bound for resolution of two incoherent optical point sources. In this work, we investigate resolution of point sources by a microsphere. Based on the spatial-mode demultiplexing scheme, we find that the resolution of the point sources can be improved using modes selection. Then, we present an executable method to realize modes selection in far-field domain for improving the resolution of the point sources under a microsphere. Our results will be helpful to improve the contrast and resolution of microsphere super-resolution imaging.
