Virtual ghost imaging with partially coherent hyperbolic cosine Gaussian beam through turbulence

摘要

Based on the classical optical coherence theory, a single detector virtual ghost imaging (VGI) with partially coherence hyperbolic cosine Gaussian beam has been demonstrated theoretically. An analytical imaging formula is obtained and the numerical calculation results lead to the influences of the turbulence strength, the propagation distance and the coherent parameters of the beam on the imaging quality. Moreover, we find that the VGI with hyperbolic cosine Gaussian beam can resolve the target better than the VGI with the conventional Gaussian Schell model beam under similar conditions.
