Paper Abstract

We propose a laser manipulation (optical tweezers) system for controlling microscopic objects by using a liquid crystal (LC) optical device with variable focusing and beam deflection properties. The focused spot, that is the position of the trapped particles can be controlled and moved by the change of the optical properties of the LC optical device by applying the voltage to the LC cell.
