Researchers have fabricated a new kind of air-filled optical fiber bundle that could greatly improve endoscopes used for medical procedures like minimally invasive surgeries or bronchoscopies.

Any fiber optic assembly that consists of more than one fiber optic in a single cable is defined as a fiber optic bundle. A bifurcated fiber assembly is the most common example of a fiber optic bundle ...

The optical fiber bundles employed in microendoscopy are normally limited to 2D imaging, primarily because size constraints make the use of tunable focusing optics problematic. A project at ...
