多脉冲增益调制三维实时成像系统

小型化是激光三维成像系统走向应用必须解决的重要问题之一。介绍了采用高重复频率小型激光器实现的小型化增益调制三维实时成像系统。利用多脉冲积累方式,使用单脉冲能量5 μJ的激光器实现了与以前单脉冲能量10 mJ增益调制系统近似的作用距离和系统测距精度,同时系统的整体体积大大缩小。对系统的作用距离与测距精度进行了测试,结果表明,在当前条件下,室外能见度5 km时,系统可达到超过100 m的作用距离,室内测试获得的系统测距精度优于3 m。

Abstract

System size is of great concern when the laser ranging system is put into practical usage. A multi-pulse gain-modulated three-dimensional imaging system is presented,which uses low pulse energy laser as illumination source. By utilizing multi pulse accumulation method,a 5-μJ pulse laser source was used to achieve a detection range of 100 m with light fog and range accuracy greater than 3 m during indoor experiment . With the using of low pulse laser source the system size is greatly reduced.
