Abstract:
An imaging fibre bundle is demonstrated for spatially-multiplexed probe beam
delivery in OCT, with the aim of eliminating the mechanical scanning currently
required at the probe tip in endoscopic systems. Each fibre in the bundle
addresses a Fizeau interferometer formed between the bundle end and the sample,
allowing acquisition of information across a plane with a single measurement.
Depth scanning components are now contained within a processing interferometer
external to the completely passive endoscope probe. The technique has been
evaluated in our laboratory for non-biological samples. Images acquired using
the bundle-based system are presented. The potential of the system is assessed,
with reference to SNR performance and acquisition speed.
