Abstract

The object of this paper is to discuss the fundamental limitations and the change of limiting resolutions of electro-optical systems operating in an atmospheric turbulent field. A fast-scanning interferometer was built to measure the time-averaged MTF's and the turbu-lence structure function coefficient CN² of a simulated turbulent medium. A computer-aided analysis system was used to measure the difference in contrast functions of the imaging system between the system (internal) noise and the atmospheric (external) noise. Psycho-physical experiments were also conducted to study subjectively the system performance under the influence of the atmospheric turbulence. The correction probability of the variables was analyzed and finally the change of limiting resolution of the electro-optical system was dicussed.
