WALL SURFACE STRUCTURE IN VISUALIZATION SPACE

摘要

PROBLEM TO BE SOLVED: To visualize fine particles that could not be visualized before by reducing reflected lights and scattered lights significantly comparing with those in a conventional visualization space in which wall surfaces are black and improving visual sensitivity. SOLUTION: In the visualization space to visualize floating fine particles or an air flow by irradiating a light, at least a part of the wall surfaces of the visualization space faces to the side of the visualization space and comprises a wall surface 1 which is an aggregate of cylindrical elements 2 in which at least parts facing to the visualization space are black.
