摘要

本文通过对塑料闪烁光纤阵列在高能X或γ射线下的特性研究

分析了利用闪烁光纤阵列作为高能成像探测器的可能性。采用了基于蒙特卡罗的模拟方法

分析了闪烁光纤在高能射线下所成图像的质量

并且模拟计算了表征图像质量的信噪比（SNR）

探测量子效率（DQE）以及调制传递函数（MTF）。通过这些计算得到闪烁光纤阵列有着传统闪烁屏所不具有的一些特性

把闪烁光纤的这些特点应用于高能成像中是完全可行的。

Abstract

Fundamental characteristics of the plastic-scintillating fiber (PSF) for wide energy range of electromagnetic radiation (X & γ) have been studied to evaluate possibility of using the PSF as an imaging detector for industrial purposes. Monte-Carlo based simulation program (GEANT4.5.1

2003) was used to generate the data. In order to evaluate image quality of the detector

the fiber array was irradiated under high energy and flux and Signal-to-Noise Ratio (SNR)

Detector Quantum Efficiency (DQE) and Modulate Transfer Function (MTF) were obtained. From the analysis

we have found that some properties of PSF are different from those of traditional screen-film

and can conclude that it is possible to apply PSF to the imaging of high-energy incident beam.
