3-D visualization of the medium movement at mesh region of helical gears is presented. The authors have advanced research aiming at using airflow in lubrication. The smoke wire method and a metallic/plastic gear pair were used in previous works, but it was hardly to observe airflow in the mesh area of high rotation gears because the mesh area was blind spot ; smoke was spread quickly. Therefore, 2-D visualization using water tank and transparent PMMA helical gears was carried out. In this paper, the authors present 3-D visualization method using characteristic of optical devices. Tracer particle images are transformed with positions. This phenomenon is called the astigmatism in optical science. We can estimate for 3-D position of tracer particles by 2-D image analyzing.
