PURPOSE:To prevent traffic disturbance due to fog by arranging a laser beam irradiation device on a road, airport, or harbor, and by irradiating laser beam when fog is generated and visualizing the optical axis of laser reflected and scattered by the fog. CONSTITUTION:The fog produced by a fluid nozzle 3 of a fog generating device 2 is adjusted via a honeycomb wall 5 by compressed air of a certain flow supplied from an air supply pipe 4, and sent into a wind tunnel 1. The laser beam irradiated by a laser beam irradiation device 6 is reflected and scattered by the fog particles, and the optical axis is visualized by emitting red light. |
