摘要
介绍了一个用塑料闪烁光纤（直径为１ｍｍ）组成的二维射线成像系统。用９０Ｓｒ放射源的β射线照射不同图案的准直器得到了清晰的图像，初步结果表明该成像系统的空间分辨率好于１ｍｍ。
? A two-dimensional imaging system of β-rays is presented in this paper The scintillating fiber has a diameter of 1mm and an aperture angle of 337° Clear images of various patterns of collimators were obtained with a β-ray source, with a spatial resolution of 1mm
