Abstract : Holographic Interferometry was attempted as a means of monitoring surface erosion and rejected because of large signal-to-noise problems. A new type of common path diffuse point interferometer has been developed to profile (electrode) surfaces. Initial studies show that the stability of this interferometer is at least two orders of magnitude better than what has been seen with standard Michelson's interferometer. Some measurements carried out with this interferometer are reported here.
