Theory and Practice of Infrared Technology for Nondestructive Testing (Hardcover)

An indispensable resource for the use of infrared thermography in industrial nondestructive testing

Machine vision, especially infrared thermography, provides industries with a more efficient and cost-effective method of detecting production flaws than traditional means of human inspection. The trend in industry today is toward inspecting and evaluating products in a nondestructive manner. For that purpose, infrared thermography has become a prime means of ensuring quality without damaging product. This comprehensive reference for professionals provides total coverage of infrared thermography inspection, theory, and practice in nondestructive testing (NDT).

Xavier Maldague provides a comprehensive introduction to Thermographic Nondestructive Testing (TNDT) and its current applications, followed by major sections on the fundamental concepts, passive and active thermography, and case studies in industry. A complementary package called IRNDT is available on the Internet for use with problems at the end of each chapter or as a tool for image processing. Detailed coverage includes:

• Introduction to thermal emission and heat transfer
• Infrared sensors and optics fundamentals
• Images and image analysis
• Experimental concepts
• Active thermography and quantitative analysis: pulsed, step, lockin, and vibrothermography
• Case studies in passive and active thermography
