摘　　要：脉冲激光测距机体积小巧、测距时不需要辅助目标 ,因此便于携带且操作简单。但由于受到计时器计时精度的限制 ,脉冲激光测距的精度相对较低。而高精度脉冲激光测距系统往往难以达到低成本和便携的要求。为此 ,介绍一种时间比例放大法用来提高脉冲激光测距精度 。The pulse laser ranger is of small volume. During the ranging, the axially target is not needed. So it is portable and the operation is simple. But, because the limitation of the accuracy of the time counter, the accuracy of the laser ranging is relatively low and the laser ranging system with high accuracy can't reach the requirements of being portable and low cost. So, the paper presents the time scale amplifying method to enhance the accuracy of the pulse laser ranging. In this way, a portable laser ranging system with high accuracy and low cost can be developed.
