Abstract

The optical scattering characteristics of marine suspended particles not only directly affect the propagation characteristics of laser in seawater, but also serve as an important theoretical basis for optical monitoring of marine environment. In this paper, different experimental schemes and theoretical calculation methods were designed for the Au and ZnO nanoparticles dispersed in seawater with different sizes and shapes according to the angle distribution of scattering intensity. The results show that the angular distribution of scattering intensity of Au nanorod is different from the numerical results based on Mie scattering or Rayleigh scattering theory. In addition, at a specific wavelength, the angular distribution of scattering intensity of the seawater dispersion solution of ZnO nanospheres shows an obvious forward propagation characteristic, and when the particle diameter increases from 10nm to 200nm, the forward scattering intensity gradually dominates.
