Compact THz based systems for neuroscience applications

继EPSRC基金EP/H 015795/1和FP 7项目No 285974 'TERA'之后，我们的团队开发了用于THz源的新型紧凑型半导体量子点激光器和天线，并在THz研究及其应用领域获得了出色的设备和经验。在这个项目中，我们将实施我们所有现有的设置和知识，以覆盖太赫兹区域-从0.1到5太赫兹。我们的THz时域光谱（THz-TDS）设置和光泵THz探测实验的初步实验表明，看到和解决光谱特征的能力，以及他们的微小和快速的变化。这项研究计划的一个主要部分将是对生物样品实施这些技术，不仅进行直接的光谱和THz-TDS测量，而且进行各种泵浦探测实验，涉及手头的各种光源，用作泵浦或探测光束：光泵浦-THz探针、THz泵浦- THz探针、IR泵浦- THz探针以及泵浦和探针光束的其它组合，以检查对细胞培养物和组织的影响。该项目的主要目标是开发清晰简单的脑结构识别诊断工具，并研究生物材料的太赫兹辐射治疗特性。

Following the EPSRC Grant EP/H015795/1 and FP7 project No 285974 'TERA', our group has developed new compact semiconductor quantum-dot lasers and antennas for the THz sources, and acquired an outstanding equipment and experience in the field of THz research and its applications. Within this project, we will implement all our existing setups and knowledge to cover THz region - from 0.1 to 5 THz. Our preliminary experiments with THz time-domain spectroscopic (THz-TDS) setup and optical-pump-THz-probe experiments showed the ability to see and resolve spectral features, as well as minor and fast changes in them. A major part of this research programme will be to implement these techniques for biological samples and perform not only straightforward spectroscopic and THz-TDS measurements, but also all kinds of pump-probe experiments, involving all broad variety of sources at hand to serve as either pump or probe beams: optical pump -THz probe, THz pump - THz probe, IR pump - THz probe, and other combinations of pump and probe beams to check the affect onto cell cultures and tissues. The main target of the project is to develop the clear and simple diagnostic tools for structural brain recognition and investigate the THz radiation treatment properties on bio-materials.
