摘要

基于毕奥-萨伐尔定律,本文给出了利用环形线圈所激发的磁场测量距离的理论依据,并设计制作了环形线圈测距仪的试验样机.结果表明,测试距离在15~ 40 cm 范围内,误差不超过5%,基本能够实现设计效果.

Abstract

According to the Biot -Savart law, the theoretical basis of the distance measured by the magnetic field of loop coils is proposed,and a range finder based on the magnetic field of loop coils is designed and made.The experimental results have about error within 5% when the measuring distance is in the range of 15 ~ 40 cm,which can basically achieve the design effect.
