Paper Abstract

Active thermographic studies proved their capabilities for detection of deeper subsurface details with reduced non uniform emissivity problems for defect detection. In this contribution analysis of subsurface anomalies has been carried out by probing a suitable frequency component with sufficient energy. This paper highlights the comparative analysis of different non-stationary thermographic schemes on the basis of probing equal energy to the chosen frequency component used for the analysis of a carbon fiber reinforced plastic (CFRP) sample used in experimentation. Experiments have been carried out to find the detection ability of different excitation schemes and comparisons have been made by taking signal to noise ratio (SNR) of the defects into consideration.
