What is infrared reflectography in art?
Infrared reflectography is the method of seeing beneath a painting’s surface to collect valuable information on a work of art. Short wave infrared cameras are a valuable tool for IR reflectography; this type of photography is similar to visible photography, as both detect reflected light.
What is infrared technology?
IR wireless is the use of wireless technology in devices or systems that convey data through infrared (IR) radiation. Infrared is electromagnetic energy at a wavelength or wavelengths somewhat longer than those of red light. Some engineers consider IR technology to be a sub-specialty of optical technology.
What is infrared light used for?
Infrared imaging, or infrared thermograph, is used in various applications. For instance, night-vision devices use IR radiation to allow humans to see in the dark. IR imaging can also be used in biological applications such as observing the changing in blood flow as thermal monitoring and regulation.
How do art historians use infrared light?
Infrared reflectography allows curators, restorers and art historians to “see through” paint layers to detect underdrawings, pentimenti, retouchings, signatures and dates. Curator using infrared reflectography to examine a painting.
Does infrared light damage paint?
Infrared thermography (IR) covers the spectrum of 3 to 14 nm and gathers information from a painting by exposing it to an infrared source and documenting the heat exchange pattern. On canvas paintings, prolonged heat exposure can damage a painting so alternative solutions must be found.
Why can IR be used to look beneath the painting?
Why can IR be used to look beneath the painting? Infrared light has a longer wavelength than visible light, allowing the materials to become transparent when they are opaque to visible light, including paints and oils.
What are the dangers of infrared waves?
Medical studies indicate that prolonged IR exposure can lead to lens, cornea and retina damage, including cataracts, corneal ulcers and retinal burns, respectively. To help protect against long-term IR exposure, workers can wear products with IR filters or reflective coatings.
What are the disadvantages of infrared technology?
Disadvantages of Infrared sensor :
- Infrared frequencies are influenced by hard articles (for example dividers, entryways), smoke, dust, haze, daylight and so on Thus it doesn’t work through dividers or entryways.
- Infrared waves at high force can harm eyes.

Can we authenticate a painting?
Painting authenticity can be achieved by taking the painting to a reputable knowledgeable expert, specializing in painting authentication. Before traveling with your painting to gain an authentication, which may damage it, there are requirements the dealer or seller will have before authenticating it.
