Paper Abstract

We present a new and precise method how to employ a periodic interference illumination for axial particle position determination. Particle movement with respect to the interference structure of illumination is followed by changes in the light field scattered by the particle. Analyses of these changes together with their calibration provide an excellent way how to determine not only the particle position with respect to the camera but especially with respect to the illuminating field structure. The algorithm was used in a standing wave optical trap for determination of the trap properties and particle behavior even in the standing wave in motion.
