Influence analysis of radiative properties and flame temperature reconstruction based on optical tomography
The flame temperature measurement is significant to study flame structure. However, during the detection process using light field imaging technology, the influence of radiative properties on flame distribution at different positions is hard to evaluate. Therefore, this study simulates the light field imaging of section flames to analyze the influence of radiative properties on flame distribution. A tomographic image is reconstructed from three-dimensional light field imaging, which is evaluated as similar to the section flame images. Then the temperature reconstructed from the tomographic image is compared to the known temperature, with a small relative error, under 10%. In addition, the influence of radiative properties on the accuracy of reconstructed temperature is also analyzed. (C) 2018 Elsevier Ltd. All rights reserved.
