Ghost imaging of Gaussian Schell pulse beams propagation in the slant non-Kolmogorov turbulent channels
چکیده انگلیسی

Lensless ghost imaging with Gaussian Schell-mode pulse beam through a slant non-Kolmogorov turbulent atmosphere channel has been studied, based on the optical coherent theory and the extended Huygens–Fresnel integral. The analytical ghost-imaging formulas have been derived by the approximation of the form of spatial–temporal coherence function of the laser field in the product of the spatial and temporal coherence function, and the quadratic approximation of the wave structure function. Based on these formulas, we find that the image quality is influenced by the turbulence strength, the propagation distance, the zenith angle of communication channel, the fractal constant of the non-Kolmogorov power spectrum of atmospheric turbulence, the pulse duration of source and the coherent parameters of the partially coherent light.
