A 女仆AV researcher has received a $2.5 million U.S. Department of Defense grant to continue his research<\/a> to conceal and manipulate the energy that materials emit.<\/p>\n The work has implications in creating nighttime camouflage that conceals objects from infrared vision, as well as in methods for anticounterfeiting, tagging and energy management.<\/p>\n \u201cAny material always leaves behind an infrared signature based on its temperature,\u201d says Debashis Chanda, an associate professor in UCF\u2019s NanoScience Technology Center<\/a> and principal investigator of the research.<\/p>\n \u201cIf we can change the signature of a material, engineer the surface in such a way that it doesn’t emit certain wavelengths or does emit others, that not only helps us to improve concealment but also anticounterfeiting applications,\u201d Chanda says. \u201cAnd controlling thermal emissions plays a role in energy management because we could actually change the amount of energy dissipated from the surface so energy can be saved.\u201d<\/p>\n The technology works by using nanoscale structures on chosen combinations of material stacks that can be adjusted to control which wavelengths of light are emitted.<\/p>\n For night vision, this means creating a material that doesn\u2019t give off an infrared signature, thus concealing it from cameras that look for infrared signatures in the dark when visible light isn\u2019t available.<\/p>\n For anticounterfeiting, this means placing a material with a certain wavelength signature on an object so that the signature can only be read with a device tuned to detect that signature.<\/p>\n The $2.5 million funding over 5 years will allow Chanda and his team to further research how light interacts with matter and also scale up their work to create materials, such as paint, that can conceal energy signatures over larger areas and explore ways to keep materials cool by controlling their energy emissions.<\/p>\n As part of this research, Chanda\u2019s group is acquiring a more than $500,000 complex scattering near-field optical microscope that includes nanoscale Fourier transform infrared spectroscopy, IR nano-imaging, atomic force microscopy-based infrared spectroscopy and ultrafast pump-probe modules. This will allow them to study electron and photon propagation, dynamics, scattering and interaction with materials.<\/p>\n \u201cThese delicate measurements can now be done inside a single instrument in a coherent manner to further understand light-matter interactions for efficient infrared emission control,\u201d Chanda says.<\/p>\n Previous work by the Chanda group has demonstrated that its technique can be used to conceal<\/a> or detect<\/a> coded information.<\/p>\n Chanda has joint appointments in UCF\u2019s NanoScience Technology Center, Department of Physics<\/a> and College of Optics and Photonics<\/a>. He received his doctorate in photonics from the University of Toronto and worked as a postdoctoral fellow at the University of Illinois. Chanda joined 女仆AV in Fall 2012.<\/p>\n","protected":false},"excerpt":{"rendered":" The work has implications in creating nighttime camouflage and methods for anticounterfeiting, tagging and energy management.<\/p>\n","protected":false},"author":199,"featured_media":111039,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"lazy_load_responsive_images_disabled":false,"footnotes":"","_links_to":"","_links_to_target":"","_wp_rev_ctl_limit":""},"categories":[5,23,24],"tags":[1112,10899,3277,3279,3280,3715],"tu_author":[],"class_list":["post-111037","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-colleges","category-research","category-science-technology","tag-creol","tag-department-of-physics","tag-nanoscience","tag-nanoscience-technology-center","tag-nanotechnology","tag-physics"],"yoast_head":"\n
