Paper Abstract

Moire tomography is applied in fully quantitative measurement of temperature distribution. Rotary moire deflectometer is designed to capture multidirectional optical projections, and moire patterns of temperature field can be obtained in 180 degrees. Then the temperature distribution of axisymmetric or asymmetric flow field is calculated by a new iterative reconstruction algorithm. The algorithm is derived from an existing moire deflection formula and based on an improved algebraic reconstruction technique. The method is demonstrated by reconstructing a temperature field generated above the top of two electric solding irons.
