Infrared Camera Technology Used in Archaeology

Technological advancements have transformed many fields and industries. The digital imaging world is no exception. Infrared camera technology enables a non-contact device to perceive infrared energy and translate it into an electronic signal. The electronic signal is then processed to produce a thermal image that can be used in performing temperature calculations. Lately, infrared innovations have been used in automatic functionality, infrared software development, detector technology, and the incorporation of built-in visual imaging. These innovations have delivered economical thermal analysis solutions. Usually, our vision is restricted to just a small percentage of the electromagnetic spectrum. The infrared camera technology overcomes this restriction, through the use of thermal energy, which has a longer wavelength compared to visible light. It becomes easy to detect what human eyes cannot see. For instance, Infrared cameras reveal tattoo-covered mummy priestess at a place called the Hathor. The professionals were able to identify the different tattoos on her body, such as the one on the neck, approximated to be 3,300 years old. Other tattoo symbols consist of snakes, locust, flowers, and cows. Cameras that utilise infrared technology see through layers and can reveal the initial image of the skin. This camera technology has provided satisfying solutions to various imaging challenges faced by most archaeologists and we are all looking forward to more intriguing discoveries using this technology.
