This work presents a novel, real-time capable, 10-channel Multispectral Advanced Narrowband Tokamak Imaging System installed on the TCV tokamak, MANTIS. Software and hardware requirements are presented together with the complete system architecture. The image quality of the system is assessed with emphasis on effects resulting from the narrowband interference filters. Some filters are found to create internal reflection images that are correlated with the filters' reflection coefficient. This was measured for selected filters where significant absorption (up to 65% within ∼70 nm of the filter center) was measured. The majority of this was attributed to the filter's design, and several filters' performance is compared. Tailored real-time algorithms exploiting the system's capabilities are presented together with benchmarks comparing polling and event based synchronization. The real-time performance is demonstrated with a density ramp discharge performed on TCV. The behavior of spectral lines' emission from different plasma species and their interpretation are qualitatively described.

MANTIS：用于聚变等离子体的实时定量多光谱成像系统

这项工作展示了一种安装在 TCV 托卡马克、MANTIS 上的新型、实时、10 通道多光谱高级窄带托卡马克成像系统。软件和硬件要求与完整的系统架构一起呈现。系统的图像质量评估重点是窄带干涉滤光片产生的影响。发现一些过滤器会产生与过滤器的反射系数相关的内部反射图像。这是针对选定的过滤器测量的，其中测量到显着吸收（在过滤器中心约 70 nm 内高达 65%）。其中大部分归因于过滤器的设计，并比较了几种过滤器的性能。量身定制的实时算法利用系统' s 的功能与比较轮询和基于事件的同步的基准一起展示。实时性能通过在 TCV 上执行的密度斜坡放电来证明。定性地描述了来自不同等离子体种类的谱线发射行为及其解释。
