Abstract

This paper presents the design, implementation, and

evaluation of an optical fiber imaging based tomographic system

for the 3-D visualization and characterization of a burner

flame. Eight imaging fiber bundles coupled with two RGB chargecoupled

device cameras are used to acquire flame images simultaneously

from eight different directions around the burner. The

fiber bundle has 30k picture elements and an objective lens with

a 92? angle of view. The characteristic evaluation of the imaging

fiber bundles and the calibration of the system were conducted

to ensure the accuracy of the system. A new tomographic algorithm

that combines the logical filtered back-projection and the

simultaneous algebraic reconstruction technique is proposed to

reconstruct the flame sections from the images. A direct comparison

between the proposed algorithm and other tomographic approaches

is conducted through computer simulation for different

test templates and numbers of projections. The 3-D reconstruction

of the cross- and longitudinal-sections of a burner flame from

image projections obtained from the imaging system was also

performed. The effectiveness of the imaging system and computer

algorithm is assessed through experimental tests.
