Paper Abstract

The primary characteristics of light scattering by water medium and small particles are analyzed based on the scattering theory. Compare the differences between two method to fix the deflection angle, one is Rayleigh expressions, the other is sampling the H-G function. The light scattering intensity distribution on conditions of variety of wavelengths and particle's semidiameters are calculated using Mie scattering expressions. The emluator of photon moving underwater is completed, which is validated taking exponential attenuation law of beam transmitting as standard, then several set of simulations proceed, accordingly some rules of underwater optical echo signal are concluded. In the end, the attenuation experiment of beams in different wavelengths, and the experiment of pulse laser detecting underwater air bubble film are conducted.
