There is successive exposition of principles to фототермической radiometry/of spectroscopy and laser thermography in a book - perspective direction in spectroscopy and thermovision. New method of researches aerophare registration of eaten up energy is the basis of in the investigated environments at affecting them of laser radiation. The modern state and prospects of development of new direction are expounded in detail, his advantages and borders of applicability as compared to other фототермическими methods. Theoretical bases of method of modulation and impulsive фототермической radiometry, her different modifications, are considered, including resonant and pump - probe фототермическую radiometry and thermography. Numerous examples of practical realization of фототермической radiometry and laser thermography are made in the different areas of science and techniques, in particular for telemetering of temperature of objects, research of слабопоглощающих environments, controlled from distance discovery and authentication of track amounts of substance, non-destructive control of materials and coverages, measuring of their thermophysical parameters. The questions related to the features of application of method for control of quality of semiconductor materials come into question, for example, in part of discovery subsuperficial defects and admixtures, measuring of their concentration and energy of activating. The special attention in a book is spared to possibilities of method as it applies to such practically meaningful areas, as medicine and biology.A book is counted on the wide circle of specialists, working in area of spectroscopy, laser physics, chemistry, biology and also can be useful to the teachers, graduate students and students of senior courses corresponding specialities.
