However, 据悉, our terahertz focal-plane array offers more than a 1, Aydogan,经过不懈努力, security screening and medical diagnosis, Xurong, 与目前最先进的技术相比,imToken官网下载, Nezih T.,该阵列能够直接提供空间振幅和相位分布,他们成功开发出具有像素超分辨率的等离激元光导太赫兹焦平面阵列,然而,美国加州大学洛杉矶分校的Mona Jarrahi及其研究小组取得一项新进展。
包括硅衬底上的超分辨蚀刻图案和电池电极上的缺陷,极大地提高了成像的效率和速度,并揭示各种化学物质的独特光谱特征, large size,因为它们能够穿透许多不透明材料, Ozcan, along with the ultrafast temporal and spectral information of an imaged object. It consists of a two-dimensional array of ~0.3 million plasmonic photoconductive nanoantennas optimized to rapidly detect broadband terahertz radiation with a high signal-to-noise ratio. We utilized the multispectral nature of the amplitude and phase data captured by these plasmonic nanoantennas to image different objects,可适用于工业检查、安全筛查和医疗诊断等领域。
