Computational lensless ghost imaging in a slant path non-Kolmogorov turbulent atmosphere

Based on the computational ghost-imaging arrangement with “virtual detector” and the extended Huygens–Fresnel integral, lensless ghost imaging with fully spatially incoherent light radiation through a slant turbulent channel has been studied. The analytical ghost-imaging formulas have been derived. Our formulas shown that the image quality is influenced by the turbulence strength, the propagation distance, the zenith angle of communication channel and the fractal constant of the non-Kolmogorov power spectrum of atmospheric turbulence. In the case of the short-exposure imaging and the bucket detector detection for test field, the influence of the atmospheric turbulence on the quality of the ghost imaging mainly come from the path which is ahead of object.
