摘要：

We derive new results on the polarization properties of a matched fiber-coil (i.e., one beat length per turn) immersed in a magnetic field. We show that both components H(y) and H(z), perpendicular to the coil axis, can be simultaneously measured. Sensing coils of 1-cm diameter, with multiple turns of fiber have been fabricated. Using 100-turn heads, we have achieved a sensitivity of 0.01 Gauss for the vectorial fiber sensor.
