Description
Summary:A charged-particle manipulator was designed and fabricated with an integrated imagingcamera allowing real-time in-situ monitoring of trapped particle motion even when the trapdevice is under motion or rotation. The trap device was made of two co-axial electrically conductivetubes with diameters of 5.5 mm and 7 mm for the inner tube and outer tube, respectively; theimaging camera with its optical fiber bundle was integrated within the tubular trap device to realizea single instrument functioning as a manipulator. Motion of suspended microparticles of 3 mu m to 50 mu m in diameter can be monitored using the integrated camera regardless of the trap device orientations. This manipulator provides capability of controlled manipulation of trapped particles bytuning the operating conditions while monitoring the feedback of real-time particle motion. Imagingof suspended particles was not interrupted while the manipulator was translated and/or rotated. This integrated manipulator can be used for charged particle transport and repositioning.
