Lensless ghost imaging with hollow-Gaussian modulated incoherent sources in atmospheric turbulence

Abstract

Abstract Lensless ghost imaging (LGI) with hollow-Gaussian modulated incoherent sources through atmospheric turbulence is investigated theoretically. The analytical formula for the point spread function of the LGI system with the hollow-Gaussian source through atmospheric turbulence is derived. By using the anti-turbulence properties of the hollow-Gaussian source, it is shown that the resolution of LGI under atmospheric turbulence can be obviously improved by properly increasing the beam order of the hollow-Gaussian incoherent source when compared with that by using traditional incoherent source.
