The promising applications of terahertz are driving the modern research towards the development of practical and low-cost terahertz imaging systems. Very recently, fully integrated terahertz imaging chip-sets have become a possibility owing to the developments in silicon process technologies. However, terahertz direct detector focal-plane-arrays (FPAs) have limited imaging applications because of the lack of phase information. Recently, researchers have started to use light-field techniques in visible light incoherent imaging for dynamic viewpoint generation. The overall objective of T-Field is to investigate and develop the light-field imaging capabilities for terahertz radiation. In this first of its kind research, we use the lens integrated 1k-pixel CMOS direct detector FPA to discern the directional information from incoming terahertz radiation. We synthesize research in electro-magnetics, optics, computer vision and image and signal processing to design T-Field instrumentation hardware and computational framework from the ground up, leading to the world's first terahertz light-field camera array.

太赫兹的应用前景正在推动现代研究朝着实用、低成本的太赫兹成像系统的方向发展。最近，由于硅工艺技术的发展，完全集成的太赫兹成像芯片组已经成为可能。然而，太赫兹直接探测器焦平面阵列(FPA)由于缺乏相位信息而限制了成像应用。最近，研究人员开始在可见光非相干成像中使用光场技术来动态生成视点。T-field的总体目标是研究和开发太赫兹辐射的光场成像能力。在这方面的首次研究中，我们使用透镜集成的1k像素的cmos直接探测器焦平面来识别入射太赫兹辐射中的方向信息。我们综合了电磁学、光学、计算机视觉以及图像和信号处理方面的研究，从头开始设计T-field仪器硬件和计算框架，导致了世界上第一个太赫兹光场相机阵列。
