Measurements of flame temperature distribution by the use of a colored array CCD (charge-coupled device) (I) the measurement of a two-dimensional projection temperature field

The make-up and basic principles of a flame temperature measuring system using colored array CCD (charge-coupled device) are described along with an analysis of its major error sources. To cope with these error sources, the authors have come up with respective resolution methods or correction algorithms. Finally, test measurements were made, which indicate that this measuring method is easy to use and features a relatively high precision.
