| 摘 要： | 为了提高现有照相系统的图像品质，对使用CCD探测器的法国客体(FTO)照相布局进行了优化，获得最佳图像品质因子下的照相布局。研究结果为:在模糊实验测量结果和高斯分布近似下，系统放大倍率为2.0；后保护器件距离客体50 cm；系统布局总长与探测系统的噪声相关，噪声越大，布局总长越短，最优布局总长的范围为3~5 m；实验验证了这一结果。

| Abstract: | The paper investigates the layout optimization for flash radiography with scatter using CCD to improve the imaging quality. The best layout is gained with the best factor of merit. The best magnification of the radiography system is 2 with the experimentally measured blur and Gaussian style assumption. The distance from the object to back windows is 50 cm. The best system length is related to the noise, and more noise leads to shorter system. The range of the best length is 3 to 5 m. The test has verified the above results. |
