Аннотация:A method has been developed to measure temperature variations in rocks to determine the stressed state of rocks. A system of equations for thermoelastic measurements has been presented. A number of advantages,in using this method, is discussed. In particular, it should be noted that this method is a non-contact one and, secondly, by using IR optics, due to the focusing of lens, averaged information can be obtained.
