湍流介质中光像抖动的频率相关

本文运用“马尔柯夫近似”获得了光在湍流大气中传输时,接收系统焦面上像斑抖动频率相关函数的一般关系式和弱光束湍流扩展区域内像斑抖动频率相关函数的解析式,同时讨论了光像抖动与光源波长的相关问题.

Quivering frequency correlation of optical images of laser light propagating in the turbulent medium

Che quivering frequency correlation function of optical images formed by a receiving system is obtained by means of the Markov approximation. The source is a laser beam propagating in a turbulent atmosphere. An ,analytic form of the frequency correlation function of the optical image quivers of laser beams propagating in the region of weak beam turbulent broadening is also obtained and the problem optical image quivers depending on the wavelength of the optical source is discussed.
