光谱层析成像法重建温度场

介绍一种用高速分层摄像控制系统重建火焰温度场的方法。连续的三维发光体可以看成若干个互相平行的二维发光断层的组合 ,对发光体某断层进行聚焦摄像 ,得到的图像是该断层的高斯像和其它断层的离焦像的叠加像。对不同断层分别快速聚焦摄像 ,得到一组辐射图像 ,采用图像反演算法 ,可以重建各断层的原始图像 ,运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

Reconstruction temperature field by spectrum sectioning t omography

Rest ruction 3-D flame temperature field using one stationary camera system with high speed is put forward in the paper .The basic of this technique is that a 3-D object can be regarded as a series of 2-D parallel sections to combine, Focusing some section, a overlapped image of itself Gauss and other sections' defocused will be captured. While moving camera along a line to shift focused section, a group of overlapped section images then will be attained. By reconstruction algorithm to rebuild each section and primary colors to measure temperature, temperature then could be three-dimensionally reconstructed. Experimental results reveal that this technique is reasonable.
