Multi-bottle beam optical trap and its light field regulation
In this study, the relationship between the position of an optical trap and the deflection angle of a reflector was studied using an optical system that can produce a multi-bottle optical trap. The position of the optical trap could be arbitrarily changed by adjusting the deflection angles of both the mirror and reflector for accurate capture and trapping of particles. Based on the theory of diffraction integral and matrix optics, the light field distribution of the incident light source passing through an optical element was analyzed and calculated. When the relationship of angles is

= 90°, the positions of the transformed optical traps are all on inclined straight lines. When the angles of deflection of the two mirrors are

22.5 °, respectively, the four-bottle trap can be transformed to one of 12 bottles. The gradient and scattering forces of the formed optical traps were calculated, and the Monte Carlo method was used to verify that the Rayleigh particles had stable captivity in a very small area in the center of the optical trap. This work shows that studying the precise trapping of multiple particles in multi-bottle optical traps is of great significance.
