摘要

Development of a non-intrusive particle tracking technique is considered. Evaluation of the existing methods show that they are not suitable for three-dimensional motion tracking. A novel system based on the principle of magnetic induction coupling is presented. This technique can be used to track the position and orientation of a single particle in a three-dimensional flow of a mass of particles. The system consists of two or more small transmitters, powered by small batteries, mounted inside the particle, and six or more receivers which acquire the induced voltages. This paper presents details of the techniques used to derive the position and orientation information from the voltages induced in the receivers. The feasibility of the proposed technique is established through simulated and actual experiments. Practical issues such as the effect of signal noise are considered. The technique presented here has a wide range of applications due to its non-intrusive nature, and is particularly useful when optical techniques are not feasible. Directions for future work are provided.
