Investigations of space-time characteristics of optical signals under conditions of multiply scattering

The space-time structure of the impulse laser radiation, distorted because of the multiply scattering is considered in the paper aiming at the investigation of the multiply scattered impulse radiation in scattering mediums, in that number, the system of ocean-atmosphere with a waved boundary between them. As a result the gamut of the small-angular diffusion approximation applicationly to the description of the space-time structure of the impulse radiation has been widened. The method for the calculation of statistical characteristics of the optical radiation has been suggested. The software created makes it possible to calculate energy and time parameters of impulse signals in optically dense mediums with the help of simple analytical approximations. The paper results have been introduced into operation. The operativeness of the calculation of time parameters in impulse signals has been increased. The paper results may find their field of application in optical lines of communication, distant laser sounding of atmosphere and oceanAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
