Capture of microscopic objects by contour optical traps formed by 4-channel liquid crystal modulator
Abstract
The efficiency of the contour optical traps generated by the 4-channel liquid crystal modulator for the manipulation with both transparent and absorbing particles has been experimentally studied. The maximum velocity of the substrate movement at which the captured particle is kept in the optical trap was used for the traps efficiency estimation. The obtained data show the ability of the effective capture of transparent objects with the ring traps even in the course of the objects boundary (periphery) being under the impact. The possibilities of a smoothly control of the size and the form of optical traps for increasing of the capture efficiency have been demonstrated.
