The predetermined model includes a forward solution to an equation describing the condition and is linearly separable in at least two dimensions corresponding to the first and second dimension. The model includes an inverse solution to the equation to provide a set of coefficients corresponding to a set of basis functions of the forward solution based on the first and second set of parameter measurements.I/ IV Fig. 1 - - - - - - - - - - - - - - - -obtain first calibration set of predetermine how many coefficients to parameter measurements from ---- include in the set of coefficients 110 first plurality of sensor locations corresponding to the set of basis functions obtain first set of parameter measurements apply transform to first from first plurality of sensor locations along -- 120 calibration set to identify - 112 first dimension of outside surface of coefficients corresponding to component high energy spatial frequencies obtain at least second set of parameter measurements from second plurality of | obtain at least second sensor locations along second dimension of 130 calibrationset ofparameter 13 outside surface of component plurality of sensor locations %| process first and second set of parameter measurements to develop continuous wall -- 140 % apply transform to second condition profile using predetermined model calibration set to identify 114 coefficients corresponding to high energy spatial frequencies. provide set of coefficients with inverse solution to equation based on first and --- 143 second set of parameter measurements generate continuous wall condition profile with forward solution to equation -- 147 with set of coefficients. identify from continuous wall condition 150 profile the condition within the component --- display on - 160 provide an alert if -- 170 display device above threshold
