Paper Abstract

We have developed an optical tweezers system by on-demand operation. In this work, we achieved real-time displacement of a trapped particle together with a fixed trapped array of particles. The displacement of a trapping beam spot was performed by introducing the phase shift method. The coexistence of the displacing beam spot with the fixed array of beam spots was realized by time-multiplexing operation of a spatial light modulator.
