The Theory Analysis and Experiment Measure of Lateral Optical Trapping Force

摘要

In non-equality optical field, we use the RO model, which is based on the theory of geometric optics, the optical trapping force which is in Y axes way on the micro sphere particles in the Mie scattering field is calculated quantitatively. The simulation results under given parameters are described. According to the simulation results, the relations between the optical trapping force and the main parameters of the system, including focus corset radius and the laser wave-length are discussed.
