We describe the procedure, and show how the combination of experimental measurement of properties of the trap coupled with computational modeling, can allow unknown parameters of the particle - in this case, the refractive index - to be determined.5 pages, 4 figures, presented at 17th AIP Congress, Brisbane, 2006Opticstext
