Measurement, Uncertainty and Lasers

The measurement of values is fundamental in science and technology. Not only does this book include the importance of uncertainty, accuracy and precision of measurement, it also explains how laser technology has helped improve measurement and redefine standards. Masatoshi introduces the concept of the measurement uncertainty in both a qualitative and quantitate manner, whilst including key equations and formulae. It discusses the SI units, standards and the importance of using lasers for measurement in modern metrology, including the redefinition of SI units over time; which culminated in the agreement to redefine the Kilogram, which takes effect in May 2019. Real case studies are included, from the implications for measuring times at the Olympics, to the impacts in criminal investigations.
