Abstract
Super-resolution imaging under passive illumination is always a crucial issue to be addressed. Because the wavefront of an incoherent light field is not easily detected, it is hard to achieve super-resolution imaging by synthetic aperture under passive illumination. In this work, we proposed a super-resolution method based on phase constructive. We use a quadrature phase-shifting algorithm to retrieve the wavefront from a series of correlation patterns and reconstruct the super-resolution image with a wavefront synthesis algorithm. A simulation result verifies the effectiveness of our proposed method with a USAF-1951 target as the object.
