Abstract: Discrete transitions in the position of a particle optically trapped in the vicinity of an interface are observed using a nanometer position sensing system. These discrete transitions in the position with distance from the interface are attributed to interference effects due to reflection and scattering of the trapping laser beam from the interface and the particle. The discrete transitions occurred at uniform intervals of similar to400 nm, corresponding to the spacing of standing wave nodes of the trapping laser beam. (C) 2004 American Institute of Physics.
