Paper Abstract

This paper describes improvements to a Hilger gauge block interferometer, including a fiber optic feed for a traceable laser radiation, automatic wavelength selection, and a CCD camera for fringe observation. The gauge measuring process is now semi-automated, computer controlled, more accurate and significantly faster and easier to operate than the original design.
