3-Dimensional temeprature imaging in flame with the focusing tomography

摘要

In this study the Focusing Tomography is presented to reconstruct 3-dimensional temeprature distributon in flame.A 3-dimensional flame could be ocnsidered as the combination of many 2-dimensional parallel uluminous sections.Focus on these discrete sections respectively by a single camera system,a group of images would be captured to form governing equations of irradiance.After many image operations in spatial and its frequency domain,the irradiance and temepraturt distribution of differnet sections could be decoded from the recorded images.Teh described technique in this experimentation applies two lightbulbs simulating two flame sections.Reasonable rsults demonstrate that this technique could provide qualitative and even quantitative information in 3-dimensional flame measurement after further developed.
