Findings

Successful experimental demonstration of beam splitter-free ghost imaging

Theoretical validation of the new ghost imaging method

Potential application with sunlight as a light source

Abstract

Many significant results have been achieved in the fields of ghost imaging, in which the beam splitter is an indispensable optical component. This paper introduces a method to realize ghost imaging without beam splitter. And we study this method experimentally and theoretically. Finally, we suggest that our device can be applied to implement the ghost imaging when we use the Sun light as the light source.
