Abstract:
OCT probes for endoscopy typically use a single optical fibre to deliver light
to the measurement region. 2D imaging is achieved using mechanical scanning
components at the probe tip. We are investigating an OCT system in which fibre
imaging bundles replace the single probe fibre, allowing many thousand
measurement points to be addressed without any mechanical scanning at the probe
tip, over a region measuring a few millimetres in each dimension. This allows a
small-diameter, electrically passive probe to be engineered using offthe- shelf
scanning optics. Images from a single-fibre, conventionally- scanned probe and
from a bundle-based probe are presented, using swept-source processing centred
at 1330 nm.
