A microscope small enough to fit into a needle creates many new possibilities
for optics in medicine. We have developed a range of optical coherence tomography
(OCT) needle probes. Connected to an OCT scanner via a single mode fiber, the probes
are constructed by fusing exact lengths of no-core fiber and graded-index fiber to
focus a broadband light beam. We terminated the optics with anglepolished,
gold-coated no-core fiber to deflect the beam. Encased in a needle (outer diameter
310 ?m), these probes are capable of 3-D imaging. However, the important
developments of 2012 have been where we have taken these needle probes.
