Light field imaging with a plenoptic camera offers a straightforward method for capturing three-dimensional information about a flow with a single camera. Chemically reacting flows are a subject of great interest in the aerospace industry; however, there is little research regarding the imaging of combustion processes or flames with a plenoptic camera. A preliminary investigation into the viability of three-dimensional flame measurements with a plenoptic camera is conducted. A high-level overview of the key concepts undergirding the plenoptic camera is given. Three-dimensional deconvolution is described as a promising volume reconstruction technique. Some initial results are presented. Preliminary conclusions are shared with a brief discussion of the direction of future work.
