摘要 在几何光学近似下 ,对米氏球状粒子所受轴向光阱力进行了数值计算。仿真结果给出了轴向稳定捕获区域和光阱力与光镊系统主要参数的关系。分析表明 ,激光束束腰半径越小 ,势阱越深 ;相对折射率、激光波长、功率等参数对光阱力也有一定影响。 Under the approximation of geometric optics,the axial force exerted on the Mie microsphere particles is simulated.The capture range and the curves of simulation are shown.The results show that decreasing focus spot radius leads to deeper optical traps and that relative refractive index,laser wavelength and power also have some effect on optical trap,which give some reliance on choosing parameters in experiments.
