Abstract:
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 rebuild each section. Temperature related to image parameter of flame can be three-dimensionally reconstructed. Experimental results are given finally.
提出了一种测量三维火焰温度的新方法.根据光学分层成像理论, 三维火焰可以看成若干个互相平行的二维发光断层的组合.用高速摄像控制系统沿着某一固定方向对火焰进行分层聚焦摄像, 得到一组辐射图像, 每个图像都是其对应断层的聚焦像和其它断层离焦像的叠加像, 运用图像反演算法, 即可重建各断层的原始图像, 再用彩色三基色测温方法, 处理所得到的原始图像, 即可建立火焰的三维温度场.通过蜡烛火焰的试验, 验证了该方法的可行性.
