Abstract

A diffraction-limited condition limits the spatial resolution of the imaging schemes. In this paper, we discuss incoherent illumination and imaging in terms of the second-order correlation to improve the resolution and reconstruction quality. A comparison of performance based on conventional imaging in free space, the average intensity of the speckles with incoherent illumination, and the intensity correlation of the imaged speckles is discussed and examined by simulation tests of these three cases. Simulation results for imaging in two cases viz. conventional imaging and with second-order correlation measurement are presented and discussed. The approach can be used to enhance the quality of reconstruction in quantitative imaging and microscopy.
