Peter Coates joined NPL in 1966, having gained a BSc at Cambridge and a PhD at Imperial College working with shock tubes. On joining the National Physical Laboratory he initially constructed ultra-fast timing circuits for measuring the time of emission of radiation from atoms, a skill he took with him when he joined the temperature section to measure the emission of photons from poorly radiating surfaces by counting individual photons. He transferred to the Temperature Section in 1972, to apply his expertise in photon counting to the NPL primary photoelectric pyrometer built by T. J. Quinn and M. Ford. He was able to make significant improvements in precision use of photomultipliers in the days before silicon photodiodes became established. He and his colleagues, Terence Chandler and John Andrews, also improved the performance and use of pyrometric lamps, including feedback stabilisation of the radiance, and they made the first and most accurate determination of the freezing temperature of palladium for many years. Peter succeeded Terry Quinn as Section head in 1975, while continuing his work in pyrometry. He was an excellent theorist, and produced two or three seminal papers in pyrometry, notably exposing the weaknesses of multiwavelength methods, which had been much trumpeted as overcoming the difficulty of unknown emissivity, showing that it is fundamentally based on an unjustified extrapolation to zero wavelength and that passive techniques alone could not solve the problem. In the early 1980s, dissatisfied with the frustrations of management, he made a second career change and moved to the NPL Time and Frequency group, where he remained until his retirement. He meanwhile drafted most of an authoritative and muchneeded book on 'Radiation Pyrometry', as he preferred to call it. Since his death in 2013 the book has been completed by Dr David Lowe, a current practitioner at NPL. David Lowe gained a BSc in Physics at the University of Wales College of Car
"""‘The Fundamentals of Radiation Thermometers’ starts by giving a thorough introduction to the basics of thermometry and the fundamental thermal radiation laws, providing clear explanations that will be useful for any undergraduate studying thermodynamics. Having established a solid set of foundations, the book then describes what is needed to make world-leading temperature measurements, providing design considerations when building radiation thermometers and reminding the reader of techniques that will help to attain optimum performance. Clearly written and meticulous, this book provides a wealth of information that can be utilised by any radiation thermometrist - from new scientists taking their first steps in this field to those with more experience. This is a great book that I wish had been available when I first started!"" —Martin Dury, National Physical Laboratory ""Coates and Lowe aim to provide a firm theoretical background for radiation thermometry and radiation thermometer design and they manage to perform this task successfully and to a very high standard. Diverse areas of physics and engineering are pulled together cohesively, in addition to the authors’ own contributions which are specific to radiation thermometry. Assembling this information would otherwise be a huge task even for the most experienced of radiation thermometer users, designers or researchers to do themselves. Providing a theoretical basis for radiation thermometers and thermometry, this book explores the link between the local measurements and traceability back to the SI in addition to a survey of the techniques for reducing measurement uncertainty and dealing with the variety of challenges found when using these devices to make measurements outside the controlled conditions of a lab. This text will be of great use to many professionals and academics. In particular, workers at the National Measurement Institutes will find this book provides suf"
