Abstract. This paper details an investigation into the use of an alternate sonic thermography inspection process which uses both low-energy acoustic coupling and an inexpensive microbolometer camera to detect barely visible impact damage in composite structures. The impetus is to create a system that is affordable, robust, rugged and easy to use in the field. This paper shows that the new system is capable of detecting barely visible impact damage with a performance comparable to that of conventional sonic thermography.
