Fiber optic polymer cure sensor
Journal of Lightwave Technology, 1988An in situ method is presented for monitoring the curing of polymeric compositions, including epoxy- and polymide-based composites. The sensor measures the difference between the refractive index of the cured and uncured composition, with the index increasing as polymerization proceeds.

Fiber-optic sensor for humidity
Optics Letters, 1989A novel fiber-optic humidity sensor is described. It is based on reversible sorption of water from the ambient atmosphere in a porous thin-film interferometer that sits on the tip of a fiber. The sorbed water changes the refractive index of the thin films and thus the reflectivity of the interferometer; the resulting modulation of the reflected ...

There has been a great deal of interest in fiber-optic sensors for some time. These devices can replace several of the less reliable mechanical ones, and they usually require a small (physically small) form factor. This chapter will present a discussion of the principles of operation of a number of sensors and several equations that govern their ...
