The report presents a solution to the problem of light scattering on randomly oriented particles of irregular shape for particles with sizes of 100, 140, 170, and 200 μm for a wavelength of 0.532 μm for various refractive indices. The solution was obtained within both the framework of the physical optics method (for the exact backscattering direction) and within the geometric optics approximation (for the scattering angles within the range from 1 to 179 deg). The obtained solutions made it possible to build a diagram of the dependence of the geometrical albedo of a particle on the maximum degree of polarization to test the Umov effect. It has been shown that if the imaginary part of the refractive index less than 0.001, the Umov effect is performed with good accuracy. However, for the case when the imaginary part of the refractive index is greater than 0.001 and the specular component of the scattered radiation begins to dominate in the solution, the Umov effect is violated. The obtained results are interesting for optical data processing. [ABSTRACT FROM AUTHOR] |
