      Miniaturized magnetic-driven scanning probe for endoscopic optical coherence tomography

      We designed and implemented a magnetic-driven scanning (MDS) probe for endoscopic optical coherence tomography (OCT). The probe uses an externally-driven tiny magnet in the distal end to achieve unobstructed 360-degree circumferential scanning at the side of the probe. The design simplifies the scanning part inside the probe and thus allows for easy miniaturization and cost reduction. We made a prototype probe with an outer diameter of 1.4 mm and demonstrated its capability by acquiring OCT images of ex vivo trachea and artery samples from a pigeon. We used a spectrometer-based Fourier-domain OCT system and the system sensitivity with our ...

      Miniaturized endoscopic probe for optical coherence tomography with a tiny magnet driving device

      This paper proposes an endoscopic probe for optical coherence tomography (OCT) applying on side-imaging of internal organs. The probe consists of single-mode fiber, a gradient-index (GRIN) lens, and a mirror of cylindrical wedge shape attaching to a magnetized metal piece by epoxy with a short steel wire. For OCT scanning, we use magnetic field generated by a larger magnet externally to drive the rotation of the magnetized metal. Compare with other probes, our probe design has two distinct advantages: 1) The exit beam will be unobstructed during 360 degree circumference scanning because there are no connecting wires in the scanning ...
