Optical Archimedes Screw Along Arbitrary Trajectories

Optical conveyors of airborne particles were previously demonstrated using different techniques allowing particles to be conveyed along straight trajectories either down or upstream the laser radiation direction. Here, the operation of an optical conveyor which has the geometry of an Archimedes scre...

Description
Summary:Optical conveyors of airborne particles were previously demonstrated using different techniques allowing particles to be conveyed along straight trajectories either down or upstream the laser radiation direction. Here, the operation of an optical conveyor which has the geometry of an Archimedes screw whose central axis is a predefined arbitrary trajectory in 3D space allowing to convey particles along any desired paraxial trajectory, is demonstrated. Herein, the operation of an optical conveyor for air‐borne particles which has the geometry of an Archimedes screw curving along a predefined arbitrary paraxial trajectory is demonstrated.
