中文译文
激光是20世纪人类历史上的一项重大发明，至今不到四十年时间，无论是激光技术本身还是相关的应用技术，尤其是军用激光技术，都取得了突飞猛进的发展。激光凭借自身方向性好,单色性好,亮度高和相干性高等优点,在各个领域得到应用，尤其在测距方面。激光具有良好的抵抗电磁波干扰的能力，在这点上要远优于超声波和雷达，尤其是在测量距离较长的时候，激光测距的优越性更为明显。

英文原文
Laser rangefinder principle
Laser is the 20th century in the history of mankind is a major inventions, still less than four years time, whether the laser technology itself or related application technology, especially the military laser technology, has achieved rapid development. Laser with their own direction, monochromatic, high brightness and coherence in various fields of applications, get in, especially in the distance. The laser has good resistance to electromagnetic interference ability, far better than ultrasonic and radar measurement, especially in the longer time, the superiority of laser rangefinder is more obvious.
