Abstract

The characteristics of surface required to ensure fitness-for-purpose depend greatly on the particular functions to be performed by that surface. Although still widely used, the electroniccontacting stylus leaves much to be desired in terms of ease of use, area coverage and cost. Alternative means for assessing surface texture including roughness, waviness and flaws have been widely studied in recent years in an attempt to produce a measuring system in keeping with the requirements of modern manufacturing. A review of the methods of operation of optical sensors, including an account of their principal advantages and disadvantages, will be presented together with an indication of how recently developed methods might overcome some of the application problems.
