This moment, the electromagnetic radiation energy (observation value) received by the remote sensor is triggered not only by the substance temperature and also by the stress. Separating quantitatively these two kinds of electromagnetic radiation energy and then inversing the actual temperature state and stress state of a medium is a matter with practical significance in earthquake prediction and stability monitoring for the large-scale geotechnical engineering. In this paper the principle and the mathematical method for inversing stress by using multiband remote sensing data are discussed in detail. A calculation example is listed.展开更多

If thisphysical phenomenon also exists in steel materials, the stress on the steel building and itsdistribution can be measured by remote sensing method. Therefore, we have made experi-ments on the steel materials, which have led to the result that the infrared radiant energyand the microwave radiant energy of the steel materials vary with the stress state of steelmaterials.展开更多
