Thermography refers to the visualization of thermograms, and encompasses all thermographic inspection techniques regardless of the technique used. For instance, a temperature sensitive coating applied to a surface to measure its temperature fields is a thermographic inspection contact technique based on heat conduction, and no infrared sensor ...
Infrared and thermal testing refer to passive thermographic inspection techniques, a class of nondestructive testing designated by the American Society for Nondestructive Testing (ASNT). [1] Infrared thermography is the science of measuring and mapping surface temperatures.
Active thermography, particularly lock-in thermography, is widely employed for inspecting solar cells [6] [8]. While effective, lock-in thermography often requires physical contact with the solar cell for excitation. However, techniques that involve periodic excitation using light sources allow for non-contact testing of electrode-free cells.
The terms nondestructive examination (NDE), nondestructive inspection (NDI), and nondestructive evaluation (NDE) are also commonly used to describe this technology. [2] Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting ...
Infrared thermography (IRT), thermal video or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science.

Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. . This measurement provides information about physical phenomena, such as phase transitions, absorption, adsorption and desorption; as well as chemical phenomena including chemisorptions, thermal decomposition, and ...
The FDA has issued a public warning notice stating that breast thermography is not an alternative to mammography [8] and has ordered Joseph Mercola to stop making excessive claims for thermography. [9] Thermography is discouraged in North America by the American Cancer Society, radiologists and the FDA for early breast cancer detection.
