Effects of turbulence on the formation of Gaussian image and signal-to-noise ratio

摘要

The extended Huygens-Fresnel principle is used to analyze the average intensity distribution and signal-to-noise ratio of a self-luminous, incoherent object with a Gaussian pattern in atmospheric turbulence. The effects of turbulent inhomogeneities in the refractive index on the formation of the images as well as the dependence of the degradation of signal-to-noise ratio on the turbulence strength, object size, and lens radius are investigated.
