| Abstract: |
| Objective To study scattering effect of relevant dust particle size based on basic theory of mie scattering. Methods The method was mainly based on further study and research of the theory of mie scattering. The Matlab software was used to calculate the scattering intensity and the scattering phase function of the particles between 0 and 5 microns. Scattering intensity and scattered phase functions of particles with different sizes were obtained. Then, the scattering images were obtained by taking a laser shot by COMS camera. The feasibility of the program was verified by comparing the gray value of the scattering image with the weighted scattering particle function value between 0 and 5 μm. Results The scattering intensity of the particles between 0 and 5 μm and the corresponding scattering phase functions and the grayscale values of the laser grayscale images from 72 ° to 108 ° were obtained experimentally. Conclusion Comparing the gray scale value of the image with the curve of the scattering function proves the feasibility of the program. |
