摘要
通过分析磁致旋光效应,提出了利用磁致旋光效应对脉冲大电流进行测量的理论依据,列举了3种典型测量系统的光路设计.经分析,其中四光路系统是一种比较成熟的设计方案,它既没有直流和交流分量分离带来的误差,也没有偏转角正弦函数单调区间的限制,而且扩大了电流的测量范围,其应用前景广阔.
Based on the analysis of magnetic effect, the theory basis of magnetic rotation effect in measuring pulsed heavy current is concluded . The optical path designs for three metrical systems are enumerated, and the merit and flaw of every design are analyzed. The four optical paths system is considered as a mature design. It hasn＇t the error of separation between AC component and DC component. Also it hasn＇t the confine of sine function monotone interval. So the measuring scope is extended and the measuring system has well prospect.
