Abstract

A micro object with lower refractive index than surrounding liquid is subjected its motion to an optical repulsive force. The optical repulsive force is generated with a focused beam array, which is dynamically formed by a computer-generated hologram displayed on a liquid crystal spatial light modulator. We demonstrate manipulations of hollow glass spheres in water and water droplets in organic solvent using the optical repulsive forces.
