- 論文の詳細を見る
Artificially made narrow vertical cracks of various widths were detected and quantitatively evaluated using a photothermal beam deflection method (mirage detection method). In order to evaluate the influence of thermal characteristics, two test sample materials whose thermal conductivities largely differed from each other were chosen. Experimental investigations clarified that the vertical "signal amplitude depth" is proportionally related to crack widths when the crack widths are of almost the same order as the pumping beam spot size of the material.
