摘　　要：介绍了采用数字延迟线集成电路芯片和微控制器结合组成的高性价比的时间数字化测量系统。在单通道工作模式下,系统的分辨率达到 125 ps,动态量程达到 7.2 μs。该系统被用于浅水环境的机载激光测深系统。This paper describes a high-resolution and cost-effective TDC (Time-to-digital converter) system, which mainly consists of a micro-controller and a general-purpose TDC chip based on the delay line technique. The system, in high-resolution mode, reaches a resolution of 125 ps with one channel and a dynamic range of 7.2 μs. The system has been used in an airborne laser depth sounding system in a shallow-water environment.
