Optical Tweezers System by Using a Liquid Crystal Optical Device

摘要

We propose an optical tweezers system for controlling three-dimensional (3D) manipulation and rotation of microscopic particles by using a liquid crystal (LC) device with three functions of anamorphic lens properties in addition to both variable-beam focusing and deflection properties. The trapped particles suspended in the water can be moved in 3D directions and also be rotated by applying voltages to the LC lens without the use of any mechanically moving parts.
