| الوصف: | This chapter deals with the propagation behavior of infinitely extensive plane light waves after passing through, and being scattered by a (hypothetical) thin inhomogeneous atmospheric layer. The propagation behavior is examined in the near-field Fresnel space beyond the layer which, at this preliminary stage, we consider homogeneous free space. The behavior of the crucially important, two-point two-wavelength correlation function of the complex amplitudes, \(S(x^{'} , y^{'} , x , y ,\lambda^{'} , \lambda )\), is examined as the waves propagate beyond the layer. The insights and results obtained in this chapter provide a foundation for the analysis given in the next chapter, which deals with wave propagation over extended atmospheric paths. When the two wavelengths coalesce, function 0\(S(x^{'} , y^{'} , x , y ,\lambda^{'} , \lambda )\) degenerates into the atmospheric MTF, \(S(x^{'} , y^{'} , x , y , \lambda )\). For any atmospheric path, the latter function determines the resolution that can be obtained when observing over that path. The development of scintillation is examined in the space below the layer; the extent to which it occurs depends crucially on the size of the turbulence structures in the layer. |
