Abstract
As the tweezer light sources, single beam optical traps, have become a kind of important tool for non-contact manipulation of microscopic objects. The interaction of light-sheets with objects allows flow visualization, nondestructive optical sectioning and imaging of the internal subcellular features. In the framework of GLMT, based on the vector angular spectrum decomposition method, with the Lorenz gauge condition and Maxwell’s equations allow adequate determination of the Cartesian components of the incident radiated electric field components. The Bessel pincer light-sheets with characteristics of auto-focusing and self-bending, has great advantages in non-destructive optical sectioning and imaging of the internal subcellular features. The influences of the Bessel pincer light-sheets (mainly focusing on beam order and scaling parameter) acting on a dielectric sphere particle, will be discussed. The results will show the sensitivity of beam parameters (beam order and scaling parameter) to the radiation force and the negative force. Further, the present solution can be used to calculate the optical torque, which is of great importance in particle transport and rotation.
