Parametric inversion: application to measurement of temperature of a combustion chamber

The problems of nondestructive testing are often associated with techniques for solving inverse problems. In this regard the authors have developed a method of characterisation of the internal temperature of a combustion chamber. Having very few measurements available for the application, they have opted for a parametric approach. Its advantage resides in its simplicity, involving only two or three measurements and affording very rapid calculation of the temperature profile.
