Dynamic Analysis and Simulation of an Optically Levitated Rotating Ellipsoid Rotor in Liquid Medium
文献摘要：
Optical trap,a circularly polarized laser beam can levitate and control the rotation of microspheres in liquid medium with high stiffness.Trapping force performs as confinement while the trapped particle can be analog to a liquid floated gyroscope with three degree-of-freedom.In this work,we analyzed the feasibility of applying optically levitated rotor in the system.We presented the dynamic analysis and simulation of an ellipsoid micron particle.The precession motion and nutation motion of a rotating ellipsoid probe particle in optical tweezers were performed.We also analyzed the attitude changes of an optically levitated ellipsoid when there was variation of the external torque caused by deviation of the incident light that was provided.Furthermore,the trail path of the rotational axis vertex and the stabilization process of a particle of different ellipticities were simulated.We compared the movement tendencies of particles of different shapes and analyzed the selection criteria of ellipsoid rotor.These analytical formulae and simulation results are applicable to the analysis of the rotational motion of particles in optical tweezers,especially to the future research of the gyroscope effect.
