Introduction to Metrology

This book is a brief introduction to metrology, which is the practice and science of measurement. The book addresses measurement, test, calibration, methods to estimate measurement uncertainties, quality assurance of these subjects and issues related to them at an introductory level.
The book was written considering readers who are new to the field and need a fast overview, but experienced practitioners can also benefit from the theoretical background. It does not focus on a specific type of measurement technology or measurement discipline but only on the general concepts and principles common to all measurements.
This book is modest. It is not intended to be a handbook and it does not have pretension to address every issue in metrology. The book shares with the reader my point of view on metrology learned during a period of over 35 years of consulting.
