Abstract
A flow of liquid containing floating fine particles is formed in a flow path, thereby causing successive movement of the particles. A light beam having intensity distribution from a laser is focused on the liquid flow, whereby the particle is optically trapped at the irradiating position, thus being stopped against the liquid flow or being slowed by a braking force. This phenomenon is utilized in controlling the spacing of the particles in the flow or in separating the particles.
