Basics of photothermal radiometry and laser thermography

The book contains a consistent presentation of the principles of photothermic radiometry/spectroscopy and laser thermography - a promising direction in spectroscopy and thermal, The new method of research is based on a fluoretiometric registration of absorbed energy in the studied media when exposed to laser radiation on them. The current state and prospects for the development of a new direction, its advantages and boundaries are described in detail
applicability compared to other photothermal methods. The theoretical foundations of the method of modulation and impulse photothermic radiometry, its various modifications, including resonant and PUMP-PROBE, are considered
Photothermic radiometry and thermography. Numerous examples of the practical implementation of photothermic radiometry and laser thermography in various fields of science and technology are given, in particular for the remote measurement of the temperature of objects, the study of the slightly absorbing media, remote detection and identification of the tracks of material, non -destructive control of materials and coatings, and the measurement of their thermophysical parameters. Issues related to the features of the application of the method for controlling the quality of semiconductor materials, for example, in terms of detecting subsurrent defects and impurities, measuring their concentration and activation energy. Particular attention in the book is paid to the capabilities of the method in relation to such almost significant areas as medicine and biology
