外调制高精度激光测距方法研究

摘要激光测距利用的是激光很好的物理特性来进行距离测量的一种测距技术，该研究始于20世纪60年代，80年代后期转入应用研究阶段，技术日趋成熟，90年代中期，各种成熟的产品不断出现。激光测距主要采用飞行时间法来测量距离，该技术的发展围绕着提高精度，扩大测量范围，缩短测距时间等方面展开。论文介绍了激光测距的基本原理，详细介绍了外调制激光测距的原理，结合激光测距方法的特点，选用外调制激光测距进行距离测量的算法研究。研究提高激光测距的精度方法。

AbstractLaser ranging is the use of laser to carry out the physical characteristics of a good measure of a distance ranging technology, the research began in the 20th century, 60's, 80's into the late stages of applied research, technology matures, the mid-90s, a variety of mature products continue to emerge. Time of flight laser ranging method used mainly to measure the distance around the development of the technology to improve accuracy, expand the measurement range, shorten the distance and time aspects.This article describes the basic principles of laser ranging are introduced in detail the principle of externally modulated laser ranging, combining the characteristics of the laser ranging method, use external modulation laser range finder for distance measurement algorithm. Research methods to improve the accuracy of laser ranging.

Key words: laser ranging, external modulation laser ranging, laser ranging accuracy;
