Paper Abstract
An oblique incidence interferometer for measuring a non-optical surface of a gear tooth with a phase shifting method is developed. The incidence angle of a He-Ne laser is set to be 84.75 degree(s) with a wedge prism, to obtain fringe spacing corresponding to the height of 3.64 micrometers . The reference beam is piezo-electrically modulated to make phase shifting fringe analysis. A high resolution CCD camera with resolution of 1280 X 1024 is used so that about 200 fringes can be analyzed. The maximum deviation of about 420 micrometers from a plane reference surface is measured with an accuracy of 40 nm.
