提出了一种为辐射探测提供方向性的新方法。这个想法是基于这样一个事实，即探测器的响应取决于两个属性的活性成分在探测器：辐射路径长度和面积呈现给粒子通量。因此，探测器的旋转板给出了特征时间响应，其可以用于识别光子通量的方向。检测器系统的模型用于设计和构建检测器，然后对其进行评估。结果表明，这种性质的旋转探测器可以产生一个特征曲线，可用于确定一个单一的固定点源的位置。
A novel method for providing directionality for radiation detection is presented. The idea is based upon the fact that detector response depends upon two properties of the active component in the detector: the radiation pathlength and the area presented to a particle flux. Thus a rotating slab of detector gives a characteristic temporal response that can be used to identify the direction of the photon flux. A model of the detector system is used to design and build a detector which is then evaluated. It is shown that a rotating detector of this nature can produce a characteristic curve which can be used to determine the location of a single stationary point source.
