Abstract

We report an alternative approach to image and analyze a large number of adjacent, optically-bound particles without using microscope objective lenses. A dynamic assembly of polystyrene spheres were initiated by two counter-propagating laser beams and configured by fine tuning the incident angle of the laser beams. Diffraction patterns from such polystyrene sphere assembly were studied. This method offers a significantly larger field of view and faster analysis over the conventional high-power microscope-based imaging technique. The application of the diffraction technique for real time analysis of the dynamic optically bounded assembly was reported.
