2P2-J14 Automated Assembly of Dynamic Beads Array by Fusion of Image Processing and Optical Tweezers

Abstract

We propose a method of automatic assembly of dynamic beads array using optical tweezers combined with computer vision. Time-sharing optical tweezers generates and changes multiple laser trap potentials based on results of real-time recognition of dispersed beads on a cover glass to automatically trap, transport, align and sort the beads without collision each other. We can also use PC mouse for user interface to translate, rotate and expand the array in real-time. Automated forming of silica and colored polystyrene beads arrays are demonstrated.
