as researchers at the Max Planck Institute for the Science of Light (MPL) in Erlangen have demonstrated now("Flying particle sensors in hollow-core photonic crystal fibre").
"The MPL researchers sent a tiny glass bead which can literally sense different physical quantities such as electric field, temperature or vibrations through the inside of this hollow-core photonic crystal fibre.
In the beginning, the idea was to develop a radioactivity sensor for inside a nuclear power station says Tijmen Euser from the Max Planck Institute in Erlangen.
Similar tasks are undertaken often using glass fibres with embedded fibre-optic sensors. What is measured is how the light sent through the fibre is affected by an external factor.
Such a fibre-optic sensor can also be used to measure a physical quantity remotely. By wrapping the fibre around the reactor,
fibre-optic sensors could probe the entire surface of a reactor. It turns out, however, that radioactive radiation darkens the interior of conventional glass fibres
