| Research Abstract |
When the shape of a portion of the face of an object or the shape of several internal cavities of an object is unknown, the shape may be estimated by using thermal data from measurements on an accessible portion of the face. In this research, we studied such an inverse problem for the shape which may vary with time. Then we focused on the unique determination problem: whether the unknown shape can be uniquely determined from the thermal data or not. Solving the unique determination problem is firstly requested for the inverse problem. We demonstrated some sufficient conditions for the unique determination.
