Paper 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.
