Abstract
This work shows the application of a heterogeneous sensor system based on fiber Bragg gratings and optical coherence tomography to monitor the drying process of a commercial water-based acrylic varnish. The varnish mechanical deformation, thickness, and average refractive index developed in the process were monitored along 24 hours for a film with approximately 430 μm of initial thickness, allowing identification of distinct time behaviors. Tomographic images exhibited refractive index discontinuities along the total film thickness indicating the development not uniform and concurrent through the whole material volume of the processes involved in the drying kinetics.
