摘　　要：介绍了适于推广的光电脉冲计数器教学实验,学生自己动手搭建光电脉冲计数器并优化设计以提高计数上限.学生能学习信号采集的基本技能,了解影响时间响应特性的因素,并学习改善仪器时间响应特性的思路.A teaching experiment suitable for promotion was reported. The task was to fabricate an optoelectronic pulse counter and try to improve its dynamic range. In this experiment, students had the opportunity to learn the skills of signal sampling, understand the factors which might limit the dynamic range of the pulse counter and improve the time response characteristics.

关 键 词：时间响应特性 光电脉冲 计数器
