However, current THz imaging is generally based on scanning technique due to the limited intensity of the THz sources. Thus, it takes a long time to obtain a frame image of the target and cannot meet the requirement of fast THz imaging. Here, we demonstrate a single-shot direct THz imaging strategy based on a broadband intense THz source with a frequency range of 0.1~23 THz and a THz camera with a frequency response range of 1~7 THz. This THz source was generated from the laser\u2013plasma interaction, with its central frequency at ~12 THz. The frame rate of this imaging system was 8.5 frames per second. The imaging resolution reached 146.2 \u03bcm. With this imaging system, a single-shot THz image for a target object with a size of more than 7 cm was routinely obtained, showing a potential application for fast THz imaging. Furthermore, we proposed and tested an image enhancement algorithm based on an improved dark channel prior (DCP) theory and multi-scale retinex (MSR) theory to optimize the image brightness, contrast, entropy and peak signal-to-noise ratio (PSNR).<\/jats:p>","DOI":"10.3390\/s24134160","type":"journal-article","created":{"date-parts":[[2024,6,26]],"date-time":"2024-06-26T11:09:09Z","timestamp":1719400149000},"page":"4160","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Single-Shot Direct Transmission Terahertz Imaging Based on Intense Broadband Terahertz Radiation"],"prefix":"10.3390","volume":"24","author":[{"given":"Zhang","family":"Yue","sequence":"first","affiliation":[{"name":"Center of Quantum Information Technology, Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Chongqing 400714, China"},{"name":"Chongqing School, University of Chinese Academy of Sciences, Chongqing 400714, China"}]},{"given":"Xiaoyu","family":"Peng","sequence":"additional","affiliation":[{"name":"Center of Quantum Information Technology, Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Chongqing 400714, China"},{"name":"Chongqing School, University of Chinese Academy of Sciences, Chongqing 400714, China"}]},{"given":"Guangyuan","family":"Li","sequence":"additional","affiliation":[{"name":"Center of Quantum Information Technology, Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Chongqing 400714, China"},{"name":"Chongqing School, University of Chinese Academy of Sciences, Chongqing 400714, China"}]},{"given":"Yilei","family":"Zhou","sequence":"additional","affiliation":[{"name":"Center of Quantum Information Technology, Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Chongqing 400714, China"},{"name":"Chongqing School, University of Chinese Academy of Sciences, Chongqing 400714, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-5754-5153","authenticated-orcid":false,"given":"Yezi","family":"Pu","sequence":"additional","affiliation":[{"name":"Center of Quantum Information Technology, Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Chongqing 400714, China"},{"name":"Chongqing School, University of Chinese Academy of Sciences, Chongqing 400714, China"}]},{"given":"Yuhui","family":"Zhang","sequence":"additional","affiliation":[{"name":"Center of Quantum Information Technology, Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Chongqing 400714, China"},{"name":"Chongqing School, University of Chinese Academy of Sciences, Chongqing 400714, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"910","DOI":"10.1109\/22.989974","article-title":"Terahertz technology","volume":"50","author":"Siegel","year":"2002","journal-title":"IEEE Trans.
