"In summary, I'm delighted with the book as a source of well balanced practical information about an exciting technology." (Geotechnical News, 1 June 2008)

"In conclusion, the book is useful for understanding one of the technology of structural monitoring for Civil Engineering applications today available on the market. But, even more important, the book represents a good guideline for sensor placement and performance reconstruction from boundary (i.e. not internal to the structural body) measurements." (Structural Control Health Monitoring, 2010)

"This makes the book extremely useful for structural inspectors who need to understand the condition of civil structures from a structural perspective ... Based on this, it can help them to reach correct evaluations of the true condition of the structures, and in turn helps them make effective decisions on the final fate of these structures." (Can. J. Civ. Eng., 19 February 2008)

"In a nutshell, this book is recommended as a good reference and source of valuable information for basic and applied principles in long gauge deformation sensing. It embodies the valuable field experiences of the authors for sensor placement and interpretation of data. It is also written in a simple format and without very much of rigor for non-optical physics majors." (Structure and Infrastructure Engineering, 1 October 2009)

"Overall the Book is organised so that it can be used as a step-by-step guide to implement a monitoring system and includes numerous application examples on the most common types of structures, such as building, bridges, historical monuments, piles, dams, tunnels, pipelines, risers, and off-shore structures, and their most frequently monitored parameters." (TMCnet.com, 17 March 2011)

"...I recommend that you tell your structural engineering colleagues about it…. I’m delighted with the book as a source of well balanced practical information about an exciting technology." (Geotechnical News, June 2008)
