(57) [Summary] [PROBLEMS] To prevent the adhesion and growth of aquatic organisms, to prevent soiling of a desired surface, to reduce the labor for maintaining cleanliness, Prevent marine environmental pollution. SOLUTION: A light beam is transmitted through an optical transmission line, and the light beam is introduced into a transparent wall from a forehead connected to the optical transmission line, The light is transmitted along the surface of the transparent wall by utilizing the light transmittance of the transparent wall, and the light is separated along the way, and the photocatalytic reaction is caused by irradiating the photocatalyst particles previously carried on the surface of the antifouling target. Accordingly, a technique of decomposing organic matter near the photocatalyst particles to perform antifouling is adopted. |
