Abstract:In this paper, an improved long-pulse excitation infrared nondestructive testing method is proposed, and a homogeneous pulse thermography (HPT) system is built. Based on the proposed new pulse excitation system, the problem of uneven heating in pulsed infrared non-destructive testing (NDT) has been effectively improved, and the signal-to-noise ratio of thermal images has been improved. Finally, the results of the experimental analysis and discussion show that the improved pulsed infrared NDT system greatly imp… Show more
