and a quantitative evaluation of its performance will

be presented in the paper. The optical technique

and its degree of intrusiveness will be discussed and

first measurements for adiabatic conditions and a

direct comparison with already validated conductance

based wall mesh sensor technique will be performed.

The NURETH-15 conference paper should

be submitted by the end of 2012.
