We demonstrate two algorithms used forreconstructing the target's structure basedon the diffracted pulses and additionallyshow that a three-dimensional target can bereconstructed using the broadband pulsesand a Fresnel lens by virtue of itsfrequency dependent focal length. Oneadvantage of T-ray imaging is the abilityto measure the far-infrared spectralresponse of the target. To highlight theimportance of this spectral information, wedemonstrate T-ray classification imagingwith different biological samples using asimple classification algorithm and twodimensional T-ray spectroscopic images.
我们展示了两种用于基于衍射脉冲重建目标结构的算法，此外还表明，借助其与频率相关的焦距，利用宽带脉冲和菲涅耳透镜可以重建三维目标。太赫兹射线成像的一个优点是能够测量目标的远红外光谱响应。为了突出这种光谱信息的重要性，我们使用简单的分类算法和二维太赫兹射线光谱图像展示了对不同生物样本的太赫兹射线分类成像。
