What is Double-passage Imaging of Partially Coherent Objects Through Turbulent Atmosphere about?
The double-passage effects of atmospheric turbulence on the imaging quality and resolution of partially coherent objects are discussed in terms of the information content and number N of degrees of freedom of an imaging system. The d Karhunen-Loe've expansion of the generalized prolate spheroidal function is used to investigate the effective number of freedom and information content of the imaging system. When waves double-passage in week atmospheric turbulence, the object is placed in the far field of the pupil plane of the illumination-and-viewing system. If a correlation scale of an object is much larger than the turbulent coherent radius and the radius of the receiving aperture is larger than the short-term spread of backscattered propagated beam, the turbulent spread of the beam will lead to a positive effect, and there is a potential Ž . Ž . supperresolution that is the resolution or the number N of degrees of freedom and the quality or information N of the d r short-term imaging of the double-passage imaging system can be higher than that of the line-of-sight propagation system.
