Abstract: 本实用新型涉及一种能在真空紫外波段获得光谱信息时空分布图像的光谱仪器,包括入射狭缝,光栅和出射狭缝。它利用柱面光栅作为色散元件,工作于掠入射状态,通过安装水平隔板,将同一块柱面光栅划分成性能完全相同的若干段,让每一段独立工作。该谱仪可以对连续或脉冲光源实现真空紫外光谱时空分辨测量。本光谱仪可用于托卡马克等离子体的真空紫外光谱诊断,具有接收立体角易算和更接近Abel变换条件等优点。

Abstract: Disclosed herein is a method of analyzing spectrum using multi-slit member and multi-channel spectrograph using the method. The multi-channel spectrograph includes a focusing lens (12a) for focusing the focus of an objective light (2) generated in a light source (4) and passed through a specimen (3). A slit unit passes the objective light focused by the focusing lens (12a) through at least one slit formed therein. A concave grating (16) diffracts the objective light (2) passed through the slit unit. A detector unit detects the objective light diffracted by the concave grating (16). The slit unit is a multi-slit member (14) with a plurality of slits (14a). The objective light (2) diffracted by the concave grating (16) and directed toward the detector unit is moved by the movement of the multi-slit member (14).
