Photothermal imaging using photopyroelectric and dual-beam mode-mismatched thermal lens method for defect study on transparent materials

This research is carried out mainly to study the defect by comparing thermal images obtained from PPE setup and dual-beam mode-mismatched thermal lens method setup. The laser beam is optimized first to select the most suitable laser beam for thermal imaging process for PPE setup and dual-beam mo...
