Litzmann Size

Litzmann size (from the names of the authors) is a simple method for the numerical study of a beam of rays during refraction-scattering at a point inhomogeneity of arbitrary shape and concentration, in which the laws of intensity distribution, inlet and displacement of the beam can be presented in an explicit analytical form.

The size of optical inhomogeneities arising due to light scattering is limited by the requirement for the presence of a natural resonant frequency, i.e. determined by the values ​​of the parameter Q = 2k*r > Qmin. In turn, the time T for which the light rays were measured is limited by the clock capabilities of the photodetectors. In this case, optical inhomogeneities with a radius value
