Specifically, it is shown that THz possesses the unique ability for a non-ionizing radiation to reveal, at the same time, the roughness of the surface, underlying paint layers or brush strokes, and potential defects in the canvas\/paperboard.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"A paper recently published in Optics Express, shows how terahertz imaging can reveal hidden features in an art painting."}],"uid":"28490","created_gmt":"2017-01-17 19:55:50","changed_gmt":"2017-01-18 14:24:22","author":"Andrea Gappell","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2017-01-17T00:00:00-05:00","iso_date":"2017-01-17T00:00:00-05:00","tz":"America\/New_York"},"extras":[],"hg_media":{"586090":{"id":"586090","type":"image","title":"20th Century Oil Painting, \u0022After Fishing,\u0022 by Ausonio Tanda","body":null,"created":"1484749035","gmt_created":"2017-01-18 14:17:15","changed":"1484749086","gmt_changed":"2017-01-18 14:18:06","alt":"20th Century Oil Painting, \u0022After Fishing,\u0022 by Ausonio Tanda","file":{"fid":"223382","name":"AL-Picture2.jpeg","image_path":"\/sites\/default\/files\/images\/AL-Picture2.jpeg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/AL-Picture2.jpeg","mime":"image\/jpeg","size":253896,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/AL-Picture2.jpeg?itok=ylVAGH6L"}}},"media_ids":["586090"],"related_links":[{"url":"https:\/\/www.osapublishing.org\/oe\/abstract.cfm?uri=oe-24-23-26972","title":"Terahertz frequency-wavelet domain deconvolution for stratigraphic and subsurface investigation of art painting"}],"groups":[{"id":"54809","name":"Georgia Tech-Europe (GTE)"}],"categories":[{"id":"129","name":"Institute and Campus"}],"keywords":[{"id":"173231","name":"Dr. Alexandre Locquet"},{"id":"173232","name":"Dr. David Citrin"},{"id":"173239","name":"Junliang Dong"},{"id":"13161","name":"Georgia Tech-Lorraine"},{"id":"173240","name":"NDE"},{"id":"173241","name":"Terahertz Imaging"},{"id":"173242","name":"THz"},{"id":"125","name":"art"},{"id":"173243","name":"paintings"},{"id":"173244","name":"art paintings"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EAndrea Gappell, Marketing and Communications Manager\u003C\/p\u003E\r\n","format":"limited_html"}],"email":["andrea.gappell@gtl.gatech.edu"],"slides":[],"orientation":[],"userdata":""}}}
