资料介绍

在激光测距过程中,目标的反射特性和入射角差异会造成激光回波信号在幅度和形状上有很大的变化,这不仅增加了信号处理的难度,而且影响了系统的测距精度。为此,从理论上分析了脉冲激光测距的误差来源,设计了峰值跟随电路和数字滤波算法来减小测距误差。实验结果表明该设计能大大提高激光测距的精度。

In the process of laser ranging, the difference between the target reflection characteristics and the incident angle will cause great changes in the amplitude and shape of the laser echo signal, which not only increases the difficulty of signal processing, but also affects the ranging accuracy of the system. In this paper, the error source of pulsed laser ranging was analyzed theoretically. Based on this analysis, the peak following circuit and digital filtering algorithm were designed to reduce the ranging error. Experimental analysis showed that this method was of great help to improve the accuracy of laser ranging and had a certain engineering application prospect.
