Paper Abstract

A setup and algorithm for 4D tracking of microscopic particles is proposed. The particles in certain volume are detected automatically and their coordinates as well as magnitude and phase distributions saved. The saved data can be used to analyze the number, spatial distribution, size, speed and track of the particles. Calculations show that it is possible to measure the 3D position of a particle having a speed as high as 10 m/s. Experiments from 15 to 2000 fps show that high quality video reconstruction of 1 and 6 μm particle flow is possible at least upto particle density of 200 particles/hologram.
