What is real is not always as it appears. UCF researchers have found a way to hide information on materials and only make it visible to a person using the right tech./news/wp-json/wp/v2/posts/93157/n
/news/wp-json/wp/v2/posts/93157/u201cWe found we can create a surface where we preferentially control absorption of light,/news/wp-json/wp/v2/posts/93157/u201d says Debashis Chanda, an associate professor of physics, optics and nanoscience who has developed the technique./news/wp-json/wp/v2/posts/93157/n
The findings were published recently in the Nature journal Light: Science & Applications./news/wp-json/wp/v2/posts/93157/n The trick is to put the information on a surface that is riddled with nanoscale patterns, which can fool the naked eye by reflecting only a solid color rather than the intended information. To get the intended information, a person must look through an infrared lens or camera tuned to the correct infrared band./news/wp-json/wp/v2/posts/93157/n The information can also be changed so that the secret messages invisible to the human eye can appear and reappear./news/wp-json/wp/v2/posts/93157/n And not only can information be hidden this way, the information can also be changed so that the secret messages invisible to the human eye can appear and reappear. These further developments were published recently as a cover article in the journal ACS Photonics./news/wp-json/wp/v2/posts/93157/n The applications for this technology could include anticounterfeiting security, infrared tagging or infrared camouflages where, for instance, the presence of a designer label could be confirmed with a look through an infrared camera. It also has military applications, such as confirming which assets are friendly and which are enemy by tags on their surfaces that are only visible in a specific infrared band or by dynamically changing the information for infrared camouflage./news/wp-json/wp/v2/posts/93157/n
