Abstract : This paper examines an inverse problem in thermal imaging, that of recovering a void in a material from its surface temperature response to external heating. Uniqueness and continuous dependence results for the inverse problem are demonstrated and a numerical method for its solution developed. This method is based on an optimization approach, coupled with a boundary integral equation formulation of the forward heat conduction problem. Some convergence results for the method are proved and several examples are presented using computationally generated data.
