A fiber-optic sensor for monitoring the cure process of an epoxy resin has been studied. The sensor is based on the measurement of the angular distribution of light transmitted through an optical fibre inside the cured polymer which refractive index changes during the curing. For the explanation a model based on geometrical optics was developed using the reflection coeffient of the optical ray on a boundary between two dielectrics. This approach allows to obtain real imaginary parts of the cladding refractive index, thus the cross-link density the epoxy cure be monitored with a single fibre-optic sensor.
