Photothermal imaging is a non-destructive and contactless technique for testing and monitoring defect of materials. This work is demonstrated thermal images for film sample of Al, Cu, Ni, and Cu with artificial defect with sampling area of 10 mm × 12 mm (21 × 25 pixels), 10 mm × 14 mm (21 × 29 pix...
