title: Optical particle manipulation using an LC device with eight-divided circularly hole-patterned electrodes.
abstract: We propose an optical manipulation system by using a liquid crystal (LC) device with unique functions such as an anamorphic lens property, variable-focusing and deflection properties. The positions and rotation of optical trapped microscopic slender particles suspended in water can be controlled. The trapped particles can be aligned along the major axis of the elliptically shaped laser beam spot and the position of the particle can be controlled three-dimensionally.
