Neutron imaging is a powerful method for non-destructive investigations where high penetration through metals and in particular high contrast for hydrogenous materials maybe exploited. Due to the complexity of digital neutron static or video image formation, image capture conditions and parameters must be accurately selected. In this work, implementation of a new neutron imaging system based on CCD camera and LiF-ZnS scintillator is presented. The image characteristics in terms of contrast, noise and dynamic range and investigation limits of this new imaging system were studied as a function of the neutron source properties.
中子成像对于无损检测而言是一种强大的方法,可利用其对金属的高穿透性,特别是对含氢材料的高对比度。由于数字中子静态或视频图像形成的复杂性,必须精确选择图像采集条件和参数。在这项工作中,介绍了一种基于电荷耦合器件(CCD)相机和氟化锂 - 硫化锌闪烁体的新型中子成像系统的实现。研究了该新型成像系统在对比度、噪声、动态范围方面的图像特性以及作为中子源特性函数的检测极限。
