Abstract
Acoustic pyrometry is a tomographic technique for measuring the
temperature distribution of gas. As the number of lines is very
small, collocation methods with smooth ansatzfunctions lead to
a sufficiently fast reconstruction algorithm. The resulting system
of linear equations is solved using the method of Tikhonov-Phillips.
Two simple but effective methods for including a priori information
are presented and applied to artificial and to measured data.
