Outline of Final Research Achievements

In this research, in order to manipulate various micro-objects based on the multi-beam optical tweezers techniques combining with intelligent control techniques such as computer vision, we have developed a hybrid optical tweezers system which can precisely control the spatial-temporal structure of laser trap potentials in real time. The demonstrated main results are the optimal design of the three-dimensional (3D) multi-beam optical tweezers based on the time-shared synchronized scanning method with a 2-axis mirror and an electrically focus-tunable lens, the full-automated assembly and subsequent geometrical transformation of 3D dynamical micro-bead arrays using image processing techniques, the controlled 3D rotation of non-spherical micro-objects like as diatoms using optical multiple-force clamps, and so forth.
