Abstract

This paper describes improvements to a Hilger gauge block interferometer, including a fibre optic feed for a traceable laser radiation, use of a CCD camera for computer-controlled acquisition of fringe images and automatic analysis of the fringe image to obtain the fringe fraction. The gauge measuring process is now automated, computer-controlled, more accurate and significantly faster and easier to operate than the original design.
