在本文中，我们总结了一种新开发的自动读出系统，该系统由带有光学平台的显微镜组成，用于分析细粒核乳剂中记录的小于 1 μm 的带电粒子轨迹。该系统的光学器件具有高空间分辨率、落射照明和氙汞灯，对于直径达约 40 nm 的小银颗粒来说，实现足够的对比度和亮度是必需的。开发了形状识别和焦点采集方法，使系统能够识别与 10-100 keV 量级的原子核相对应的亚微米轨迹。
In this paper, we summarize a newly developed automatic readout system, composed of a microscope with an optics stage, to analyze charged particle tracks of less than 1 mu m recorded in a fine-grained nuclear emulsion. This system's optics have the high spatial resolution, epiillumination, and xenon-mercury lamp necessary to achieve sufficient contrast and brightness for small silver grains up to about 40 nm in diameter. Methods of shape recognition and focus point acquisition were developed that enabled the system to identify submicron tracks corresponding to nuclei on the order of 10-100 keV.
