In this work optical fibers anci nanometrical wavelenghts are useci to perform chemical measurements. The optical fiber is part of the optical sensor, not only as a waveguicie. This sensor emerges as a more sensible, precise anci faster option when compareci to conventional measurement anci analysis methocis. A ciye concentration sensor that uses the technique of the evanescent fielci absorption of an optical fiber is analiseci, built anci essayeci. The fiber portion, which constitutes the sensur, is a smooth transition taper, generateci by the fiber stretching by heat. This sensor operates at 633 nm for the crystal violet ciye with a singlemocie optical fiber. The theory useci to calculate the power attenuation of the sensor fiber guicieci light is presenteci. A theoretical performance confrontation of the sensor using singlemocie, multimocie, iluminateci by ciifferent light sources anci ciifl'erent taper ciimensions is realized. The sensor fabrication methoci is ciescribeci as well as the light power measurement process for some dye concentrations. The experimental results for attenuation vs. ciye concentration are presented anci compareci to the theoretical values. The essays, which refer to each one of the built tapers, have been realizeci using 5 ciifferent ciye concentrations anci, at least, 4 repetitions for each one.

On-line sensing can play an important part in controlling the quality of the final product in any manufacturing environment, including liquid composite molding (LCM). Having a sensor embedded within the part itself is often the most effective means of monitoring its condition at various stages of manufacturing and even throughout its useful life. However, given their intrusive nature, there are practical limitations imposed upon their size, quantity and trajectory within the part. This study explores the possibility of using a single lineal sensor to monitor the resin flow front during the mold filling stage of LCM, and to detect the onset of void formation and the presence of dry spots within the mold. Experiments were conducted to characterize the response of a fiber optic system previously developed for cure monitoring. Simulations were then performed to determine the optimal placement of just one such sensor in a mold to demonstrate that sufficient information on the mold filling process could be obtained. The purpose of the simulation work was to learn how to interpret the sensor response and, subsequently, use it to control the LCM process.
