摘要
文中从影响激光测距精度的因素分析入手 ,提出了最具影响力的两个因素 ,阐述了提高测距精度的途径和方法 ,简要介绍了时间间隔测量 (T .I .M )系统及其关键技术之一———模拟扩展器的工作原理 ,从理论和实例两方面分析了引进该技术对提高测距精度的实际效果 。
The factors that have an effect on accuracy of laser ranging are analysed. Two prime effect factors are presented. The approaches and methods that further improve ranging accuracy are described. The principles of time interval measure system and one of key technologies——simulative expander are introduced. From theory and practical application, the improvement of laser ranging accuracy, advantage and disadvantage are analysed, as well as the problems of notice for this technology. \;
