    Abstract

    We describe a class of diffractive optical elements that intended for use in holographic optical trapping systems to project ring-like optical traps. The ring traps' hologram is design by shape-phase algorithm, that incodes amplitude information in Fourier space into shape. The flexibility of the shape-phase algorithm leeds to several advantages over commonly used optical vorteces. While, optical vorteces carry orbital angular momentum which determines the vortex diameter, ring trap dimensions do not depend on the angular momentum. In particular, we formed a ring trap without angular momentum, or tangetial-force. Also unlike most optical vortices or ring-like Bessel beams, these ring traps have strong enough axial intensity gradients to trap objects in three dimensions. We investigated the three dimensional vortex-like trapping experimentaly and by volumetric imaging.
