Abstract

In this paper, single view fan-beam tomography using tunable diode laser absorption spectroscopy (TDLAS) is introduced for measuring axisymmetric temperature distribution. Generated by a well-collimated laser through a cylindrical lens, the fan beam laser crosses the target region and is detected by seven photodiode receivers. Under the condition of axisymmetric temperature and gas concentration distribution, the same data sets from the given view can be used for other views. For typical temperature distribution in confined combustion flow, two-dimensional image is reconstructed using algebraic reconstruction technique (ART). Given the 2% measurement error of the data, the mean error between the original temperature distribution and the reconstructed one is less than 5%, which validates the feasibility of this approach.
