The Angle Distribution of the Spheroid Particle upon Optical Surface

Abstract:

The angle distribution of the spheroid particle upon optical surface is discussed in this paper. Taking the advantage of the Bobbert-Vlieger (BV) theorem, the scattering model between optical surface and spheroid particles is established. The scattering process is analyzed and the scattering coefficients are derived by using of the vector spherical harmonic function. The differential scattering cross section (DSCS) of a spheroid particle upon the optical surface is calculated which is compared with the Discrete Sources Method (DSM) proved the validity of the method and the influences of the incident angle and scattering angle on the DSCS are analyzed numerically in details. The results show that the influence of the incident angle on the scattering intensity is less at the smaller scattering angle, which can be concluded that the influence of the incident angle is more serious to the back scattering .The polarization effect and back scattering effect become weaker and weaker with the increase of the incident angle, which provide strong theoretical foundation to the nondestructive detector engineer.
