This Small Business Technology Transfer (STTR) Phase I project proposes to develop the technological and theoretical foundation of a high-speed terahertz (THz) tomographic non-destructive evaluation (NDE) imaging system. It is proposed to construct and evaluate a multiple THz transmitter and receiver module array test-bed to be employed with a commercially availability spectrometer system. This test-bed will be configured in a tomographic configuration and initially employ 4 and 6 elements in Phase I. This test-bed will be used to evaluate 1) the functional parameters and the feasibility of gathering multiple channels of data from an array of modules driven by the same split fiber optic source; and 2) the functional parameters and the feasibility of the reconstruction of 3 dimensional tomographic images from simple test objects scanned by the array. THz imaging has shown great potential, and there is great potential for innovation and research to provide a quantum leap in imaging speed and three dimensional image reconstruction. The image formation rate and three-dimensional image construction have been identified as two of the most important enabling factors in the widespread adoption of this technology for commercial applications.THz tomography offers tremendous market potential in the fields of Non-Destructive Examination (NDE), and homeland security. THz imaging can be used for the NDE of plastic and composite materials in aerospace and other industries, to insure strength and safety of manufactured components. In addition, rapid imaging of concealed explosives, biological agents, chemical weapons, flammables, metallic and non-metallic weapons, and other potentially dangerous items are of great concern to many civilian and governmental agencies (transportation security, law enforcement), and industries such as commercial aviation. This STTR collaboration will foster the developmental collaboration between industry and university in this rapidly advancing field.

这个小企业技术转让（STTR）第一阶段项目提出了开发高速太赫兹（THz）断层无损评价（NDE）成像系统的技术和理论基础。建议构建和评估一个多太赫兹发射器和接收器模块阵列的测试平台，采用商业可用的光谱仪系统。该试验台将配置为层析成像配置，在第一阶段最初使用4个和6个元件。该试验台将用于评估：1）功能参数和从由同一分裂光纤源驱动的模块阵列收集多通道数据的可行性;以及2）功能参数和从由阵列扫描的简单测试对象重建三维断层图像的可行性。太赫兹成像已经显示出巨大的潜力，并且存在巨大的创新和研究潜力，以提供成像速度和三维图像重建的量子飞跃。成像速率和三维图像构建已被确定为该技术广泛用于商业应用的两个最重要的促成因素。THz断层成像在无损检测（NDE）和国土安全领域提供了巨大的市场潜力。THz成像可用于航空航天和其他工业中塑料和复合材料的NDE，以确保制造部件的强度和安全性。此外，隐藏的爆炸物、生物制剂、化学武器、易燃物、金属和非金属武器以及其他潜在危险物品的快速成像是许多民用和政府机构（运输安全、执法）以及诸如商业航空的行业非常关注的。这种STTR合作将促进工业和大学在这个快速发展的领域之间的发展合作。
