摘要: We discuss a technique for designing diffractive optical elements (DOE) that generate vortex beam superposition with desired number and configuration of traps. Several modifications the approach are proposed. Some configurations DOE-aided trap arrays predetermined pattern intensity minima maxima trapping transparent opaque microobjects calculated. Results real experiment on optically trapping, rotating, displacing in controlled manner multiple microparticles generated by designed DOE have been reported.
