OPTICAL FIBER LATERAL SCANNER FOR A MINIATURE OPTICAL FIBER PROBE

摘要

An optical fiber magnetic scanning arrangement for a miniature optical fiber probe is provided for various optical imaging applications. The magnetic system includes a permanent magnet piece with a magnetization direction substantially orthogonal to the own axis of the optical fiber. The permanent magnet piece extends in a direction substantially aligned with the own axis of the optical fiber, wherein the current conductor loop is adjacent an inner surface of the permanent magnet piece. In another embodiment, the permanent magnet is of a hollow cylinder type with a radial magnetization direction. The permanent magnet cylinder extends in a direction substantially aligned with the own axis of the optical fiber, the current conductor loop being placed inside the permanent magnet cylinder. The designs provide a potential for further miniaturization.
