Title:
サーモグラフィー検査手段および被試験体の表面近傍構造の非破壊検査方法
Document Type and Number:
Japanese Patent JP6726661
Kind Code:
B2
Abstract:
A thermographic examination device for non-destructive examination of a near-surface structure at a test object includes a heating device for applying heat energy to a surface region to be heated of the test object; a thermal sensor device for detecting a time profile, following the application of heat energy, of a spatial temperature distribution on a surface region to be measured of the test object, the surface region to be measured including the surface region to be heated as well as an outer surface region to be measured which is adjacent to the surface region to be heated; and an evaluator for evaluating the time profile of the spatial temperature distribution so as to detect at least one parameter of the near-surface structure at the surface region to be measured.
