Abstract
Three-dimensional position of optically trapped dielectric particles can be detected by measuring the back-focal plane interference pattern of incident and scattered fields. Time-domain surface current based near zone to far zone transformation was implemented to compute the interference pattern by a spherical scatterer under a focused Gaussian beam. Computed results are compared with experimental data for validations.
