Abstract: The capabilities and specific features of the formation and dynamic control of so-called contour optical traps using a fourchannel liquid crystal modulator are studied theoretically and experimentally. Circular, elliptical and C-shaped traps are formed. Trapping and confinement of absorbing micro-objects by the formed traps are demonstrated.

Keywords: optical traps, micro-objects, dynamic manipulation, liquid-crystal modulators, absorbing particles.
