Medical uses - Optical fibres are well suited for medical use. They can be made in extremely thin, flexible strands
for insertion into the blood vessels, lungs, and other hollow parts of the body. Optical fibres are used in a number of instruments
that enable doctors to view internal body parts without having to perform surgery.
Simple uses - The simplest application of optical fibres is the transmission of light to locations otherwise hard
to reach. Also, bundles of several thousand very thin fibres assembled precisely side by side and optically polished at their
ends, can be used to transmit images.
