What are the advantages of fibre optic detection?

Optical fibres act like light pipes. Rays of light from an emitter are directed to the intended location with minimal losses. This has a number of possible advantages.
Primarily, it allows the detection light source to be remote from the electronic device that generates the light, and this in itself has numerous advantages.

As the mounting for the tips of the fibres can be very small it means that it enables photo sensing to be used in extremely confined and otherwise inaccessible locations, where the size of a conventional transmitter or receiver would otherwise prohibit their use.

As the optic fibres are passive they can be used in hostile environments of heat, humidity, electro magnetic interference and radiation etc that might be incompatible with mounting sensor electronics directly.

As the tips of the fibres can be taken right up to their targets it is possible to use extremely narrow beams, making detection of very small objects practical and reliable.

Multi-channel Amplifiers are available that use multiple fibres to detect precise positional information of components in automated assembly systems which might not be possible with conventional sensors due to space and access limitations. Various types and sizes of fibres are available to cope with a variety of environments and applications.

These are just a few advantages, although there are of course disadvantages, eg, limited range and cost.
