Multibeam bilateral teleoperation of holographic optical tweezers

This video shows micro-bead being trapped and moved using a multibeam bilateral teleoperation system of holographic optical tweezers accelerated by a graphics processing unit. The micro-beads follow the trajectory of each haptic device, and the forces to which the micro-beads are subjected, which are generated by Stokes drag, are measured and fed back to an operator via the haptic devices. This real-time telexistence was quantitatively evaluated based on the time response of the trapped beads and the fedback forces. The demonstration of touching red blood cells shows the effectiveness of this system for biomedical application.
