摘　　要：　介绍激光脉冲测距中时间放大技术的原理和实现方法。用设计的电路进行了时间间隔模拟放大测量,测量结果和理论计算基本一致。提出时间放大电路设计中几个关健技术问题的解决方法。实验结果表明,用时间放大方法可在不提高时钟频率的情况下,将测距精度提高至分米或厘米级。The principle and technique of the time amplification in pulsed laser ranging is described. The simulated measurement is carried out by designed time amplifying circuit. The measurement result is basically in agreement with that of theory analysis. The methods for solving some key technical problems are given. The experimental results show that measurement accuracy can be increased to the order of decimeter or centimeter by using the time amplifying technique with lower clock frequency.
