High-visibility ghost imaging with phase-controlled discrete classical light sources

Abstract

We take phase modulation to create discrete phase-controlled sources and realize the super-bunching effect by a phase-correlated method. From theoretical and numerical simulations, we find the space translation invariance of the bunching effect is a key point for the ghost imaging realization. Experimentally, we create the orderly phase-correlated discrete sources which can realize high-visibility second-order ghost imaging than the result with chaotic sources. Moreover, some factors affecting the visibility of ghost image are discussed in detail.
