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.
In infrared thermography, thermal radiation is detected and measured with infrared imagers, also known as thermographic cameras or radiometers. The imagers contain an infrared detector that converts the emitted radiation into electrical signals that are displayed on a color or black and white computer display monitor.
Thermographic cameras detect radiation in the infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nm or 9–14 μm) and produce images of that radiation. Since infrared radiation is emitted by all objects based on their temperatures, according to the black-body radiation law, thermography makes it possible to "see" one's ...
Infrared thermography specifically refers to a nonintrusive, noncontact mapping of thermograms on the surface of objects using a detector that is sensitive to infrared radiation. [1] There are many other terms widely used, all referring to infrared thermography; the adoption of specific term(s) depends on the author's background and preferences.
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.
Pit vipers can detect their prey in complete darkness using specialized sensory organs that perceive infrared radiation. This ability inspired the development of thermal imaging cameras. Image ...
Infrared thermal imaging cameras or infrared cameras are essentially infrared radiation thermometers that measure the temperature at many points over a relatively large area to generate a two-dimensional image, called a thermogram, with each pixel representing a temperature. This technology is more processor- and software-intensive than spot or ...
A thermal imaging camera (colloquially known as a TIC) is a type of the thermographic camera used in firefighting. By rendering infrared radiation as visible light , such cameras allow firefighters to see areas of heat through smoke, darkness, or heat-permeable barriers.
