本专利阐述一种根据通电导线周围缠绕单模光纤中的法布里效应制成的光纤电流传感器。该传感器是由两个具有互相垂直偏振膜的半盘组成,两个半盘有45°相对角度,它可以确定偏振旋转角度。1/4盘具有一个组
This patent describes a fiber-optic current sensor fabricated from the Fabry-like effect of wrapping single-mode fibers around energized leads. The sensor consists of two half-discs with mutually perpendicular polarizing films with 45 ° relative angles to the two half-discs, which determine the angle of polarization rotation. One-fourth of the disk has one group
