Paper Abstract

One important parameter in the case of translation of an optically trapped particle is the maximum achievable speed of translation in optical trapping. While the parameter is expected to have a dependence on the particle diameter and the viscosity of the medium, there will also be dependence on the laser power and step size of the moving trap. In this paper, we will experimentally investigate the maximum translation speed of a given trapped particle in a certain medium achievable in a holographic optical trap. We will implement the holographic trap using a liquid crystal spatial light modulator with a computer interface and use latex beads in water for trapping.
