摘　　要：基于几何光学原理,在强聚焦激光光场中,以射线光学计算模型为基础,对几何尺寸远大于光波长的米氏球状粒子所受的轴向与横向光阱力进行计算.并在给定参数条件下,进行数值仿真,讨论各主要参数与光阱力的关系.By using the RO model based on the theory of geometric optics,the optical trapping force on the microsphere particles in the Mie scattering field was calculated quantitatively. The simulation results under given parameters were described and most parameters of the system and optical trapping forces connection were discussed.
