Analysis Of The Characteristics Of Laser Transmission In The Atmosphere

With the development of laser technology, laser transmission in theatmosphere have been paid more and more attention, are very important forlaser communication, laser radar, laser weapons, laser ranging, laser energytransport applications, transmission characteristics in air turbulence in thestudy of laser can be achieved using the efficiency needed laser enable better.This paper mainly studies the turbulence on laser transmission, attenuation,the beam intensity of the impact of extended light field and the wavefrontdistortion. Firstly, this paper introduces the atmospheric turbulence model,gives three kinds of typical atmospheric turbulence power spectrum model;secondly, by using the Rytov approximation and Markov approximation andstatistical optics theory, established the transmission model of laser light fieldin turbulent flow, gives the laser intensity in the turbulent middle studentsattenuation, flicker, wavefront aberration, drift transmission effect; then, thelaser transmission simulation results for typical eddy current non uniformfield are given, as well as in the typical turbulent model, the simulation resultsof the laser transmission; finally, taking into account the laser receiver system,design for laser transmission in turbulent model in an optical system, andform the simulation results.
