Abstract

Scintillator arrays are widely used in radiation detection, but imaging these arrays with a camera can introduce point-of-view (POV) effects. To better understand these effects, we present a model for light transport within scintillators shaped like a rectangular cuboid. Analytical expressions for the light projection are derived, and the impact of surface roughness is investigated using Monte Carlo simulations. Finally, benchmark measurements using bismuth germanate (BGO) scintillators validate the model’s predictions.

均匀辐照长方体闪烁体的光发射

闪烁体阵列在辐射探测中得到了广泛的应用，但是用相机对闪烁体阵列进行成像会产生视点效应。为了更好地理解这些效应，我们提出了一个光在长方体形状的闪烁体内传输的模型。导出了光投影的解析表达式，并利用蒙特卡罗模拟研究了表面粗糙度的影响。最后，使用锗酸铋（BGO）闪烁体的基准测量验证了模型的预测。

期刊介绍： The journal seeks to publish papers that present advances in the following areas: spontaneous and stimulated luminescence (including scintillating materials, thermoluminescence, and optically stimulated luminescence); electron spin resonance of natural and synthetic materials; the physics, design and performance of radiation measurements (including computational modelling such as electronic transport simulations); the novel basic aspects of radiation measurement in medical physics. Studies of energy-transfer phenomena, track physics and microdosimetry are also of interest to the journal. Applications relevant to the journal, particularly where they present novel detection techniques, novel analytical approaches or novel materials, include: personal dosimetry (including dosimetric quantities, active/electronic and passive monitoring techniques for photon, neutron and charged-particle exposures); environmental dosimetry (including methodological advances and predictive models related to radon, but generally excluding local survey results of radon where the main aim is to establish the radiation risk to populations); cosmic and high-energy radiation measurements (including dosimetry, space radiation effects, and single event upsets); dosimetry-based archaeological and Quaternary dating; dosimetry-based approaches to thermochronometry; accident and retrospective dosimetry (including activation detectors), and dosimetry and measurements related to medical applications.
