Abstract (in Japanese) (See Japanese page) 
(in English) Now in non-destructive concrete inspection, a hammering test is the most popular. But it has disadvantages that defect-judging depends on tester’s skill, and the tester needs to work dangerously in a high-place. Thus, we propose a new inspection method using a scanning laser Doppler vibrometer (SLDV) and air-coupled sound wave. We carried out experiments using concrete test pieces which have styroform board as a cavity. From the experimental results, we confirmed the feasibility of our proposed method for concrete inspection. The maximum measuring distance was also examined.
