Surface image generation using local slope-based mapping algorithm

Abstract

This paper introduces a novel technique to provide the microtopographical details of a machined surface using a fiber-optic probe. Unlike the previous methods, the present approach involves pixel-to-pixel scanning for slope measurement, which in turn generates the three-dimensional profile of the probed surface using the relevant mapping algorithm. Minute details of the surface roughness characteristics, including slope and height at different positions, can be visualized from the reconstructed surface image.
