摘要
文中阐述了脉冲激光雷达测距的原理 ,并综述了其核心技术——脉冲飞行时间测量技术及其最新进展。详细介绍了数字插入测量法的原理与其三种不同的插入方法 :延迟线法、模拟插入法和差频测相法 。
The principle of distance measurement in pulsed laser radar is introduced and its key technology of time of flight(TOF)is discussed.TOF in laser pulsed distance measurement can be measured analogically,digitally,or using an interpolation method.The interpolation method,using the digital method combined with an interpolation method of three kinds,is a suitable way to employ a wide measurement range,high precision and accuracy,and a fast measurement speed for fast laser radar.And the three interpolation methods:delay line interpolation,the Nutt and dual Nutt principles,and the digital dual Vernier method,are described in detail in this paper.
