Abstract
Holographic optical traps using the forces exerted by computer-generated holograms to trap, move and otherwise transform mesoscopically textured materials. The efficacy of the present invention is based upon the quality and nature of the diffractive optical element used to create the traps and dynamically use them. Further a landscape of potential energy sites can be created and used to manipulate, sort and process objects.
Claims13
A method for manipulation of a plurality of objects, comprising the steps of:
- providing a source of objects locomotion;
- applying the source of objects locomotion to create a pattern of potential energy wells;
- applying the pattern of potential energy wells to a plurality of moving objects, thereby trapping at least a portion of the plurality of moving objects in the pattern;
- and
- moving the pattern of potential energy wells to manipulate the plurality of moving objects, wherein the source of objects locomotion comprises a polymer walker having legs with an therebetween which respond to stimuli by changing the angle to move the legs for effecting motion of the objects.
