Abstract :
In this paper, we describe a system for tracking multiple fluorescent particles in a confocal microscope. The tracking algorithm relies on position estimates derived from fluorescence measurements taken at a small number of discrete locations combined with an LQG controller. We report experimental results of tracking a single fixed particle, a single diffusing particle, and two fixed particles.
