With their similarity to the organs of the most advanced creatures
that inhabit the Earth, sensors are regarded as being the "senses
of electronics": arti?cial eyes and ears that are capable of seeing
and hearing beyond the range of - man perception; electronic noses
and tongues that can recognise odours and ?avours without a
lifetime training; touch that is able not only to feel the texture
and temperature of the materials but even to discern their chemical
compo- tion. Among the world of chemical sensors, optical devices
(sometimes termed "optodes", from the Greek "the optical way") have
reached a prominent place in those areas where the features of
light and of the light-matter interaction show their advantage:
contactless or long-distance interrogation, detection sensitivity,
analyte selectivity, absence of electrical interference or risks,
and lack of analyte consumption, to name just a few. The
introduction of optical ?bres and integrated optics has added more
value to such sensing since now light can be con?ned and readily
carried to dif?cult-to-reach locations, higher information density
can be transported, indicator dyes can be immobilised at the distal
end or the evanescent ?eld for unique chemical and biochemical
sensing (including multiplexed and distributed measurements),
optical s- sors can now be subject to mass production and novel
sensing schemes have been established (interferometric, surface
plasmon resonance, ?uorescence energy transfer, supramolecular
recognition . . . ).
