- 論文の詳細を見る
Thermal wave tomographic imaging of an aluminum sample with a new photopyroelectric detector is reported. The new detector can detect the local ac temperature field when it comes into contact with the back surface of a sample. Compared to the capacitively coupled detector, this detector is easier to handle and has increased sensitivity to the photopyroelectric signal. The effects of the laser beam modulation frequency and subsurface defects in the sample on the tomographic image have also been studied. It is revealed that the resolution of the tomograph increases with increasing modulation frequency and decreasing metal-tip diameter of the detector.
