The Extreme Ultraviolet Spectrograph

The EUV instrument is a one-dimensional imaging spectrograph that views a vertical wedge of the sky. Using the spacecraft motion, it forms a two-dimensional image of the sky as this wedge moves horizontally in a "push-broom" configuration.

EUV仪器是一种一维成像光谱仪，它观察天空的垂直楔形部分。通过利用航天器的运动，它以“推扫”配置在水平方向上移动该楔形部分，从而形成天空的二维图像。
