Abstract

In the present investigation, an optical transducer has been developed for materials testing and evaluation of different electrochemical phenomena. The optical transducer was developed by incorporating methods of holographic interferometry for measuring microscopic deformation and electrochemical techniques for determining the corrosion current of metallic samples in aqueous solutions. In addition, the optical transducer was applied not only as an electrometer for measuring different electrochemical parameters but also, the optical transducer was applied as a 3D-interferometric microscope for detecting different micro-alterations at a metal surface in aqueous solution at a microscopic scale.
