We have started the development of the EUV optics to detect the scattered EUV emission (O II) by the Oxygen ions in the polar wind. Hydrogen absorption cell and the mirror which does not reflect Lyman-α will be the key to eliminate the Lyman α line from the Geocorona. In 2000, we have developed the extreme-ultraviolet scanner XUV boarded on the sounding rocket SS-520-2.The sounding rocket SS-520-2 was launched from the Svalbard Rocket Experiment Site on December 4, 2000, and flew under the magnetospheric cusp region. The XUV scanner designed to detect the OII emission from the polar w333ind and the ionospheric F layer was successfully operated.In spite of the fact that the XUV scanner is not necessarily very sensitive to the OII emission. the sufficient accumulation time enabled us to detect the OII emissions from the ionospheric F layer and the polar wind. This success is the first attempt to take two-dimensional images of the oxygen ion distribution around the earth via the optical remote sensing.

我们已经开始开发EUV光学元件，以检测极风中的氧气离子散射的EUV发射（O II）。氢吸收细胞和不反映lyman-α的镜子将是消除从地理器中消除莱曼α线的关键。 2000年，我们开发了在Sound Rocket SS-520-2上登机的极端粉丝扫描仪XUV。声音火箭SS-520-2于2000年12月4日从Svalbard Rocket实验站点推出，并在Magnetosphere cusp区域下飞行。 XUV扫描仪旨在检测极性W33IND和电离层F层的OII发射。尽管XUV扫描仪不一定对OII排放非常敏感。足够的积累时间使我们能够检测到电离层F层和极风的OII排放。这种成功是通过光学遥控性进行二维图像的二维图像。
