摘要

This paper presents an imaging-based instrumentation system for three-dimensional (3-D) temperature measurement of a combustion flame. A combination of image-processing techniques and two-color radiation thermometry is used to first reconstruct band-limited grayscale representations of the flame and then to determine its temperature distribution. The reconstruction process assumes rotational symmetry in the structure of the flame. A series of experiments has been conducted on a laboratory-scale combustion rig to evaluate the performance of the system. The results obtained demonstrate the capability of the system to determine flame temperature on a 3-D basis.
