摘要

为了解决传统脉冲式激光测距装置在测量精度与测量速度难以同时兼顾的问题，本文采用了一种基于数字混频脉冲式激光测距方法。该方法利用异步二分频与数字混频技术实现激光发射脉冲信号和激光回波信号的时间差的等比例放大，并通过使用通用时间数字转换器(Time-to-Digital Converter

TDC)芯片对该时间差进行精确测量。为了实现这一方法，本文设计了适用于激光发射电路的高频脉冲驱动电路与基于雪崩二极管(Avalanche Photo-Diodes

APD)的接收电路。同时，为简化电路设计，本文利用现场可编程逻辑门阵列(Field-Programmable Gate Array

FPGA) 来实现异步二分频与数字混频。为了验证本文采用测距方法的正确性，在实验室中构建了一套激光测距系统。测量结果表明，该测距系统在100~130 cm距离范围内实现了毫米级测量精度，有效解决了传统方法中测量速度与精度难以兼顾的问题，验证了方案的可行性。

Abstract

To address the inherent trade-off between measurement accuracy and speed in traditional pulsed laser ranging systems

a novel method based on digital mixing is proposed. The technique proportionally amplifies the time-of-flight interval between the transmitted laser pulse and the received echo signal by employing asynchronous divide-by-two frequency division and digital mixing. This amplified time interval is then precisely quantified using a general-purpose Time-to-Digital Converter (TDC). To facilitate this method

a high-frequency pulsed laser driver and an Avalanche Photodiode (APD) -based receiver circuit were designed and implemented. Furthermore

a Field-Programmable Gate Array (FPGA) was utilized to realize the asynchronous frequency division and digital mixing

simplifying the overall circuit design. A prototype system was constructed and experimentally validated in a laboratory environment. The results demonstrate that the system achieves millimeter-level accuracy over a measurement range of 100-130 cm

effectively resolving the conflict between speed and precision found in conventional approaches and confirming the feasibility of the proposed scheme.
