3523 非冷却マイクロボロメータによる低反射型赤外線サーモグラフィの開発(G03-14 非破壊技術,G03 材料力学)
詳細
We had applied infrared thermography to inspection of concrete structures, for preventing them from the falling accident of concrete fragment. However, the thermographic NDT has a shortcoming that the measurement results are affected by atmospheric radiation due to the sunlight, sky or surrounding materials. To reduce the influence of these disturbance noises, the infrared thermography with detectable wavelength from 5 to 8μm, which coincides with absorption range of moisture, is utilized. In this research, a new infrared thermography with 5 to 8μm wavelength range by applying a band pass filter and an uncooled microbolometer infrared array detector.
