Abstract

The double-passage effects of atmospheric turbulence on the imaging quality and resolution of an optical system , illuminated by the incoherent light ,are discussed in terms of the information content and the nUmber Nd of degrees of freedom of an imaging system. The Van Cittent-Zernike theorem and the Karhunen-Loe've expasion of generalized prolate -spheroidal function for the mutual intensity of stochastic waves is used to calaulate the turbulent average mutual intensity f12 for light from an extended incoherent quasi -monochromatic source and double-passage propagation in weak atmospheric turbulence. It is shown that , for incoherent illumination system and the receiving aperture is larger than the radius A of backscattered beam ,the turbulent spread of the beam may lead a positive effect , and there is a potential supperresolution , the resolution beyond the classical diffraction limit.
