多通道高分辨率时间记录仪

A multi-channel high-resolution time recorder system

介绍一个高速多通道时间记录仪,应用于量子密码学的研究试验中。该系统在一片FPGA完成了全部的逻辑设计,具有结构简单、精度高、速度快的特点。

This paper introduces a multi-channel and high-speed time recorder system, which was originally designed to work in the experiments of quantum cryptography research. The novelty of the system is that all the hardware logic is performed by only one FPGA. This way, the system can achieve several desirable features, such as simplicity, high resolution and high processing speed.
