| 摘 要： | 提出了用一个摄像机重建三维发光体辐射场分布的方法。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象，得到的图像是该断层的高斯像和其他断层分别聚焦摄像，可得到组辐射图像，再用图像反汪算法，即可重建各断层的辐射场。实验模拟了具有我断层的三维发光体，获得了初步结果。

| Abstract: | The Focusing Tomography is presented to reconstruct the 3 D radiation in a luminous body. The 3 D luminous body could be considered as the combination of many 2 D parallel luminous sections. Focus on each section by only one camera, a group of images will be captured which is the overlapped image of one focused image and other defocused images. The irradiances of these images form governing equations. The irradiance distribution of different sections could be induced from above equations. In this experiment, several light emitting diodes are employed to simulate several luminous sections. Results show that this method can reconstruct the irradiance of each section. |
