Abstract:

An investigation of a combined holographic-infrared inspection system is reported. Thermal loading of the inspection sample yields responses from both holographic interferometry and thermographic imaging. The combined nondestructive testing approach provides additional diagnostic information, more than can be obtained from either inspection system along. Inspection can be accomplished by real-time observation of the two images. More complete quantitative inspection information can be obtained by computer analysis of the images at various times after the thermal excitation. The inspection method is particularly useful for nondestructive testing of composite structures. Plans are being made to commercialize this SBIR development.
