Chemo-optical micro—sensing systems
نویسنده
چکیده
Chemo—optical micro-sensing systems, whether based on fiber optics or integrated optics show promising prospects. The physical principles underlying chemo—optical waveguide sensors are discussed with the accent on linear evanescent field sensors. The role of the chemo-optical transduction layer is emphasized. Restriction of the freedom of design by technological uncertainties is briefly dealt with. The structure of a complete micro-sensing system is discussed, and illustrated by presenting various designs of chemo-optical sensors based on Surface Plasmon Resonance.
