本文介绍了基于成像光纤的断层扫描系统的设计和实现，用于燃烧火焰的三维 (3-D) 可视化和表征。八个成像光纤束与两个 RGB CCD 相机相结合，用于从燃烧器周围八个不同方向同时获取火焰图像。光纤束由 30k 个像素组成，并具有 92° 视角的物镜，提供宽广的视野。进行了一系列的系统校准以确保系统的准确性。还进行了计算机模拟，以评估基于从成像系统获得的八个图像投影进行火焰横截面 3D 重建的不同断层扫描算法。在燃气试验台上获得的初步实验结果表明，该系统能够对火焰进行 3D 可视化和表征。
This paper presents the design and implementation of an imaging fiber based tomographic system for the three-dimensional (3-D) visualization and characterization of combustion flames. Eight imaging fiber bundles coupled with two RGB CCD cameras are used to acquire flame images simultaneously from eight different directions around the burner. The fiber bundle consists of 30k picture elements and has an objective lens with a 92° angle of view, offering a wide field of view. A series of system calibrations was conducted to ensure system accuracy. Computer simulations were also undertaken to evaluate different tomographic algorithms for 3-D reconstruction of flame cross-sections based on eight image projections obtained from the imaging system. Preliminary experimental results obtained on a gas fired test rig demonstrate that the system is capable of 3-D visualizing and characterizing flames.
