Finkelstein L. Measurement science – an examination of its current state and lines of advance

The paper outlines the content and organisation of the generic concepts and principles of measurement and instrumentation. It argues that recent changes of technology and the political, economic and social environments demand a review of those principles and considers the resultant challenges and lines of advance. It distinguishes between measurement and instrument science. It considers the challenges presented by applications of measurement outside the physical sciences. It highlights the effect of advances in computing and the resultant convergence the principles of measurement and instrumentation and the sciences underlying systems and information. It considers special problems of sensing and actuation. It points to the design orientation of measurement and instrumentation principles and applications of the systems approach to measurement and instrumentation. It examines indirect measurement. Problems of errors and uncertainty are pointed out. Finally it points to the approaches of knowledge management.

Keywords: measurement science, instrument science.
