The second edition of this text was published in 1999, and since that time many improvements have taken place in instrumentation performance and versatility. This third edition reviews these many changes and how they impact the way thermographers operate, deploy, calibrate, and test the new instruments. In addition, the instruments that have been made essentially obsolete are reviewed as part of the historical evolution of the technology. The purposes of this text are to: - Familiarize potential users of commercial IR sensing and imaging instruments with IR measurement and analysis basics - Provide the practical information needed for users to select the instrument most appropriate for their application. Describe how to perform valid and successful measurements in a variety of applications - Serve as a reference to help thermographers examine the validity of new applications.
