Abstract: Methods and apparatuses for tracking and correlating particles include an optical detector that captures a first and a second image of the particles. A video detector is used to capture a plurality of video frames of the particles. The video detector captures the video frames of the particles at a rate faster than the rate at which images are captured by the optical detector to track the movement of particles. A first image position of a particle in the first image of the particles is identified, and then the first image position of the particle is correlated to a second image position of the particle in the second image using the plurality of video frames.
