ABSTRACT:
An optical magnetic-field sensor has: a GRIN rod lens; optical fiber for incident light and optical fiber for outgoing light, which are arranged on one end of the GRIN rod lens; first and second reflection mirrors both being on the other end of the GRIN rod lens; and a magneto-optical crystal between the first and the second reflection mirrors, wherein light leaving the optical fiber for incident light is converted into convergent light by the GRIN rod lens , the convergent light is reflected by the first reflection mirror so that an optical axis of the convergent light is substantially vertical to the central axis of the GRIN rod lens , and that the convergent light is focused on the central axis of the GRIN rod lens , the reflected light passes through the central axis and is converted into divergent light, the divergent light is then reflected by the second reflection mirror which is placed at a position being symmetrical with the first reflection mirror, relative to the central axis, the reflected divergent light is converted into convergent light by the GRIN rod lens again to be fed into the optical fiber for outgoing light.
