Reconstruction Temperature Field of Flame by Optical Sectioning Tomography

摘要

Optical sectioning thermography is developed to measure 3-D flame temperature distribution. A 3-D flame can be regarded as a series of 2-D parallel sections. A camera moving along a line to shift focused section is used to capture overlapped section images. With these obtained images, image reconstruction algorithm is applied to rebuilding each section. Temperature related to image parameter of flame can be three-dimensionally reconstructed. Experimental results are given finally.
