Abstract :
This work shows results from the application of an optical sensor based on fibre Bragg grating to monitor the drying of paints. The drying time of the latex paint film was monitored along 370 minutes by an encapsulated fibre Bragg grating employed as transducer device for the mechanical forces inherent to the process. Along the drying, the paint film changed from a sticky liquid state to a solid state. Changes in the film during the drying are analyzed by the FBG strain sensitivity. Temperature changes were also monitored with another Bragg grating in the same optical link.
