A comparison of the application of Pulse-Compression to eddy-current and LED thermography is presented. Results achieved on a dedicated sample with an impact damage are reported and discussed. The same pulse compression procedure based on the use of Barker codes has been applied to both techniques and it proved to be work properly in both cases. Two different features have been extracted and imaged from the retrieved time-responses after pulse-compression.

Abstract

A comparison of the application of Pulse-Compression to eddy-current and LED thermography is presented. Results achieved on a dedicated sample with an impact damage are reported and discussed. The same pulse compression procedure based on the use of Barker codes has been applied to both techniques and it proved to be work properly in both cases. Two different features have been extracted and imaged from the retrieved time-responses after pulse-compression.
