The Single-Shot Femtosecond Hyperspectral Camera.

该项目的基础是由STFC IAA赠款“3D激光光谱仪”(KCD00170)和2017年6月授予的STFC IPS研究员自由支配基金提供的种子。该项目源于需要一种新的诊断方法，以支持STFC资助ST/J002011/1和ST/M007375/1的等离子体加速器研究。IAA的赠款允许建造一台工作中的单镜头高光谱相机和开发一台单镜头超高速摄像相机。这种仪器的开发吸引了寻求相机商业化的公司的注意。在仪器的研制过程中，概述了仪器的广泛应用范围，明确了今后的发展方向。STFC后续基金将证明单次激发高光谱协议(SHP)的商业能力，并促进开发负担得起的超快飞秒成像协议。该基金将允许扩展现有的概念验证相机，以适应对工业化学品的主动监测和检测的需求。据估计，每年约有13,000人死于过去工作中的化学暴露。许多死亡是可以预防的，涉及工人当时不知道的过去接触的化学物质。SHP等价格实惠且可快速部署的高光谱相机的商业化，将通过及早检测逃逸过程排放来确保职业健康和安全，同时减少代价高昂的生产停顿。高光谱化学监测还可以为优化化学生产效率和工农业产品的质量保证做出贡献。后续基金还将使新开发的超快单次高光谱协议(USHP)进入市场化阶段。该基金还将使USHP得以升级，将摄像分辨率提高100%。超快摄像技术是研究等离子体、光化学、光伏、自旋电子学、材料、流体和蛋白质生物学的宝贵工具。目前，泵浦-探测方法是超快成像的首选方法，但该方法需要重复测量才能构建视频-在探测非重复事件方面做得不够。与SHP相比，类似的超快方法，如条纹相机，成本很高，而且视频帧速率也低于SHP-SHP预计在目前的迭代中以每秒50万亿帧的速度捕获视频，这是一项新的世界纪录。商业超快成像系统的出现将使超快科学大众化--这一领域一直局限于国家实验室和超额认购的用户设施，几乎没有例外。

The basis of the project was seeded from a STFC IAA grant `3D Laser Spectrometer' (KCD00170) and a STFC IPS Fellow Discretionary Fund, awarded June 2017. The project arose from the need for a novel diagnostic to support the plasma accelerator research of STFC grants ST/J002011/1 and ST/M007375/1. The IAA grant has allowed a working single-shot hyperspectral camera to be built and a single-shot ultrafast videography camera to be developed. The development of the instruments has attracted the attention of companies seeking the commercialisation of the cameras. During the development of the instruments, the wide scope of applications was outlined, and directions of future development were made clear. The STFC follow-on fund will prove the commercial capabilities of the Single-Shot Hyperspectral Protocol (SHP) and facilitate the development of an affordable ultrafast femtosecond imaging protocol.The fund will allow extending the current proof-of-concept camera to suit the needs for active monitoring and detection of industrial chemicals. Each year around 13,000 deaths are estimated to have been caused by past chemical exposure, at work. Many of the deaths were preventable, involving past chemical exposure unbeknownst to the workers at the time. The commercialisation of an affordable and rapidly deployable hyperspectral camera such as the SHP would ensure occupational health and safety through early detection of fugitive process emissions while mitigating costly pauses in production. Hyperspectral chemical monitoring can also contribute in the optimization of chemical production efficiency and in the quality assurance of industrial and agricultural products.The follow-on fund will also bring the newly developed Ultrafast Single-shot Hyperspectral Protocol (USHP) to a marketable stage. The fund will also enable upgrades to the USHP, improving videography resolution by one hundred percent. Ultrafast videography is an invaluable tool in the study of plasmas, photochemistry, photovolataics, spintronics, materials, fluidics, and protein biology. Currently, the pump-probe method is the go-to method for ultrafast imaging, but the method requires repetitive measurements to construct a video - falling short in probing non-repetitive events. Comparable ultrafast methods, such as streaks cameras are costly and also fall short in video frame rate when compared to the SHP - which is expected to capture videos at 50 trillion frames per second in its current iteration, a new world record. The availability of a commercially ultrafast imaging system will democratise ultrafast science - a field that has been confined to national laboratories and oversubscribed user facilities, with few exceptions.
