SBIR Phase II: THz Imaging Focal Plane Array

这个小企业创新研究（SBIR）第二阶段项目是开发一个高分辨率的太赫兹成像焦平面阵列。太赫兹辐射是一个很大程度上未被探索的光谱区域，但它有很大的希望通过服装，包装和行李墙（安全应用）的能力，并根据复杂分子的组成和构象激发共振分子运动的能力，如爆炸物，非法药物和药品（成像光谱学）。目前的非制冷探测器技术在其感测THz辐射的能力和视频帧速率方面是边缘的。这项工作的预期结果是证明：（1）在高达250 Hz帧速率的操作下，噪声限制辐射检测的20至40倍的改进;（2）用于非常低成本制造全波长焦平面阵列的新技术;以及（3）高性能THz焦平面阵列。

This Small Business Innovation Research (SBIR) Phase II project is to develop a high-resolution focal plane array for terahertz imagery. THz radiation is a largely unexplored region of the spectrum, but holds great promise for its ability to pass through clothing, packaging and baggage walls (security applications) and for its ability to excite resonant molecular motions according to the composition and conformation of complex molecules such as explosives, illegal drugs and pharmaceuticals (imaging spectroscopy). Present uncooled detector technology is marginal in its ability to sense THz radiation and in video frame rate. The anticipated results of this work are to demonstrate: (1) a 20 to 40 times improvement in noise-limited radiation detection at operation up to 250 Hz frame rate; (2) a new technique for very low cost manufacture of all-wavelength focal plane arrays; and (3) a high-performance THz focal plane array.
