Roxworthy, Brian J. 2011-05-25T14:35:57Z 2011-05-25T14:35:57Z 2013-05-26T10:00:22Z 2011-05-25T14:35:57Z 2011-05 The main purpose of this thesis is to investigate the eff ects of polarization on optical forces as well as to utilize such forces in the measurement of optical properties of micro-scale particles. Theoretical aspects of optical trapping are presented and the focusing action of high numerical aperture lenses is studied in detail. Simulations are performed that quantify the x, y and z focal polarization components of conventional Gaussian beams as well as 4 cylindrical vector beams, and the simulation results are used to explain experimental optical trapping behavior of the 5 beams. In addition, the custom built optical trapping microscope is used for quantitative phase imaging of 1 um microspheres, and the results are presented as a first step toward the measurement of the optical properties of optically trapped particles.
