Christopher A. Brown, a professor of mechanical engineering at Worcester Polytechnic Institute in Massachusetts, also could be thought of as a topographic mapmaker working on a very fine scale because of his interest in the texture of surfaces. From surface-height measurements taken as a function of position, Brown, founder and director of the institute’s surface metrology laboratory, hopes to develop a way to abstract the measurements into numbers that could summarize the potentially more than a quarter million heights from a 512 × 512 array of points and help discriminate between two...Read full article

    metrology
    Metrology is the science and practice of measurement. It encompasses the theoretical and practical aspects of measurement, including the development of measurement standards, techniques, and instruments, as well as the application of measurement principles in various fields. The primary objectives of metrology are to ensure accuracy, reliability, and consistency in measurements and to establish traceability to recognized standards. Metrology plays a crucial role in science, industry,...
