高光谱太赫兹成像的实现是理解所有尺度生命科学的重要一步。这种理解的关键是从这些图像中检索介电特性,这项任务受到实验限制的困扰,二十多年来对太赫兹社区提出了挑战。在本文中,我们提出了一种新的组合检索方法,通过结合 Kramers-Kronig 关系和 Fabry-Pérot 反射模型来克服对人体骨骼样本介电特性提取的错位和 Fabry-Pérot 效应。从主要由胶原蛋白组成的约 100 µm 人骨切片中提取的结果与原始胶原蛋白样品的测量结果一致。这是将太赫兹成像应用于术前和临床实践的另一个垫脚石。
The realisation of hyperspectral terahertz imaging is a significant step towards understanding of the life sciences on all scales. A key to this understanding is the retrieval of dielectric properties from such images, a task which is plagued by experimental limitations, challenging the terahertz community for more than two decades. In this contribution, we propose a new combined retrieval methodology to overcome misalignments and Fabry-Pérot effects on the extraction of the dielectric properties of human bone samples through the combination of the Kramers-Kronig relations and Fabry-Pérot reflection modelling. Results extracted from ∼100 µm human bone slices composed largely of collagen are consistent with those measured for pristine collagen samples. This represents another stepping-stone towards the adoption of terahertz imaging into pre- and clinical practice.
