title: Properties of high-order ghost imaging with natural light.
abstract: We discuss theoretically the visibility and contrast-to-noise ratio (CNR) of high-order thermal ghost imaging with natural light. Five cases of an object beam and a reference beam with different polarized light are analyzed. Theoretical calculations show that a higher-order N can optimize the ghost imaging in both visibility and CNR in all five cases.
