用成像光纤簇进行全场光学断层扫描(OCT)测量
An imaging fibre bundle is demonstrated for spatially-multiplexed probe beam delivery in OCT, with the aim ofeliminating the mechanical scanning currently required at the probe tip in endoscopic systems. Each fibre in the bundleaddresses a Fizeau interferometer formed between the bundle end and the sample, allowing acquisition of informationacross a plane with a single measurement. Depth scanning components are now contained within a processinginterferometer external to the completely passive endoscope probe.The technique has been evaluated in our laboratory for non-biological samples. Images acquired using the bundle-basedsystem are presented. The potential of the system is assessed, with reference to SNR performance and acquisition speed.
