湍流大气中图像传输的信息量

Information Content for Imager Propagsting through Atmospheric Turbulence

分别从系统像的信息量和信息自由度的角度分析了大气湍流对相干和不相干照明光学系统成像质量和分辨率的影响．理论上，处于一定大气湍流条件下的相干照明系统存在着超出经典衍射极限的超分辨率．

The effect of atmospheric turbulnce on the imaging quality and resolution of an optical system, illuminated by the coherent and noncoherent light, are discussed by using the information capacity and information degrees of freedom of an image imaged by the system. In the special case of the atmopheric tubulence for a coherent illumination system, there is a POtential of the superresolution beyond the classical diffraction-limit
