Free-Space Terahertz Optoelectronics

9905881 Zhang该提案描述了一个为期三年的计划，用于研究改进的太赫兹光电技术及其在医学和生物成像中的应用，这是NSF CAREER奖先前支持的工作的延续。在过去的四年里，PI已经建立了一个最先进的太赫兹成像系统，并展示了其在多个领域的应用，并在太赫兹产生和检测技术的各个方面进行了创新，包括单次成像和增强强磁场中半导体的太赫兹产生，该提案的主要目标是扩展太赫兹成像仪器的能力，其空间分辨率在视频帧速率下超过400x600像素。这将使该仪器的性能提高几个数量级，从而大大提高其效用。

9905881ZhangThis proposal describes a three-year program for the investigation of improved terahertz optoelectronic technology and its applications in medical and biological imaging, a continuation of the work supported previously by NSF CAREER Award. In the last four years, the PI has built a state-of-the-art terahertz imaging system and demonstrated its applications in several areas, and created innovations in various aspects of terahertz generation and detection techniques, including single shot imaging and enhancement of THz generation from semiconductors in a strong magnetic field, The primary goal of this proposal is to extend the capability of the terahertz-imaging instrument with a spatial resolution exceeding 400x600 pixels at video frame rate. This would expand the performance of the instrument by orders of magnitude and hence greatly increase its utility.***
