We describe the implementation of the optical coherence interferometry (OCT) technique in the dynamic measurement of the deformation of polymers. The experimental set-up of the interferometer system and the signal processing used are also described. Theories and methods for measuring polymer film thickness are presented and the results are shown. In this work, the technique does not account for the determination of the refractive index.The study found that the dynamic estimation of the thickness of thin polymer films is possible and very accurate.
