Integral measurements of chemiluminescence, the light that is naturally emitted as a result of chemical reactions, in the form of camera images have been used for reconstructing the local 3-D chemiluminescence intensity field of three asymmetrically arranged unsteady Bunsen burner flames. The computed tomography of chemiluminescence (CTC) technique has been used for this purpose. The robust computed tomography (CT) algorithm, based on the Algebraic Reconstruction Technique (ART), that is used here has been extended to 3-D by Floyd and others and offers greater flexibility in the camera locations [1]. The focus of this work is to pave the way for exploring the potential that CTC holds for flames of true nature. Reconstructions of the unsteady flames have been achieved. The expected flame structure has been resolved and comparison with the original flame images demonstrates a satisfactory quality of reconstruction.
