영문 초록

  To detect defects under the surface of a acryl plate, the infrared thermography was applied. The defects of specimen were made by back-drilled circular holes. To get the large difference of temperature of the surface, a halogen lamp was used. The location of defect is a good agreement with the maximum temperature contrast. The sizes of defects are calculated by means of FWHM. In case of large defect, the sizes of defects were estimated exactly comparing to real size. FWHM was decreased with time. In case of small defect, FWHM was increased with time. The temperature contrast was initially increased and finally decreased with time in both case.
