The 2nd volume of 'Advances in Measurements and Instrumentation: Reviews' Book Series contains 9 chapters written by 21 authors from 7 countries: Brazil, China, France, India, Mexico, Russia and Spain. But it is not a set of reviews. As usually, each chapter contains the extended state-of-the-art followed by new, unpublished before, obtained results. It can be a valuable tool for those who are involved in research and development of different measuring systems.
