A new application of hyperspectral imaging (HSI) to steady-state plasma emission observations is proposed because of its prominent feature: an HSI camera records a two-dimensional image, and each spatial pixel contains spectral data typically with more than a hundred bands, while conventional digital cameras have only three bands. The characterization of an HSI camera (Specim IQ) has been performed during steady-state plasma-material interaction experiments using the linear plasma device PISCES-A. By easily subtracting the background/continuum emission in contrast to conventional filter cameras, two-dimensional images of multiple emission lines at different wavelengths are simultaneously obtained during a single measurement, demonstrating the advantage in plasma emission observations.

高光谱成像在稳态等离子体观测中的新应用

由于其突出特点，高光谱成像（HSI）在稳态等离子体发射观测中的新应用被提出：HSI相机记录二维图像，每个空间像素包含通常具有一百多个波段的光谱数据，而传统的数码相机只有三个波段。HSI 相机 (Specim IQ) 的表征是在稳态等离子体材料相互作用实验中使用线性等离子体设备 PISCES-A 进行的。与传统滤光相机相比，通过轻松减去背景/连续谱发射，在单次测量期间同时获得不同波长的多条发射线的二维图像，证明了等离子体发射观测的优势。
