Abstract
A new thermal radiation technique had been developed to detect internal flaws of mortar structure, such as building, bridge, tunnel and so on.<BR>The present study shows that stepwise solar energy was injected to the tested plate with artificial internal flaws. Transient radiation temperature image of the slit flaws on the CRT of the infrared radiometer was represented and visualized by means of the existence of the flaws with the higher equivalent radiation temperature above the flaws than that of the flat surface. In this report, it was clear that the temperature rise of the flaws was increasing with increase in width b and depth H.
