Influence of light scattering particles on optical properties of polymer diffusion plate

摘要：

　　In order to analyze the influence of scattering particles on the optical properties of light scatter of polymer diffusion plate,we establish the microspheres of scattering particles in mathematical physics model.According to Mie scattering theory,we study the relationship between the scattering intensity distribution and the particle radius,the refractive index and the wavelength of the incident light.The results show that the particle radius is larger and incident wavelength is smaller,scattering intensity distribution is concentrated; the particle refractive index and scattering intensity distribution are not a simple corresponding relationship.At the same time according to the Monte Carlo method,the simulation is also used to analysis the effect that scattering particle concentration,the scattering particle radius and refractive index influence the diffusion plate light transmission rate and uniformity.The result shows that as the particle concentration is greater and transmittance is smaller,uniformity increases first and then decreases.As the particle radius is small,light transmission rate is higher and the particle refractive index is larger,light transmittance increases first and then decreases.But the relationship of the uniformity,the particle radius and the particle refractive index are all not simple corresponding law.
