FIELD: physics.SUBSTANCE: according to the method of moving a group of opaque microobjects, a light beam with closed regions of zero intensity is formed from multiple beams. First, three coaxial, zero-order Bessel beams with different propagation constants are formed, thereby forming a stable beam in form of a circular spot. These beams are then arranged in space so as to form one or more closed regions for capturing and moving opaque microparticles.EFFECT: high efficiency owing to automation of the process.11 dwg |
