已研制出一种载于PLANET-B（NOZOMI）航天器上的紫外成像光谱仪。紫外线吸收光谱仪由光栅光谱仪（UVS-G）、吸收池光度计（UVS-P）和电子单元（UVS-E）组成。UVS-G采用平场型光谱仪，可测量110 nm至310 nm之间的FUV和MUV范围内的辐射，光谱分辨率为2-3 nm。UVS-P是一种通过吸收池技术分别检测氢（H）和氘（D）莱曼α发射的光度计。他们利用航天器的旋转和轨道运动来拍摄图像。介绍了火星紫外线观测实验的主要科学目标和紫外线观测的特点。给出了地冠和行星际莱曼α辐射的MUV光谱以及在氢莱曼α波长和170 nm背景下拍摄的月球图像，作为绕地飞行阶段和火星转移阶段UVS观测的代表性实例。
An ultraviolet imaging spectrometer (UVS) on board the PLANET-B (NOZOMI) spacecraft has been developed. The UVS instrument consists of a grating spectrometer (UVS-G), an absorption cell photometer (UVS-P) and an electronics unit (UVS-E). The UVS-G features a flat-field type spectrometer measuring emissions in the FUV and MUV range between 110 nm and 310 nm with a spectral resolution of 2–3 nm. The UVS-P is a photometer separately detecting hydrogen (H) and deuterium (D) Lyman α emissions by the absorption cell technique. They take images using the spin and orbital motion of the spacecraft. The major scientific objectives of the UVS experiment at Mars and the characteristics of the UVS are described. The MUV spectra of geocoronal and interplanetary Lyman α emissions and lunar images taken at wavelength of hydrogen Lyman α and the background at 170 nm are presented as representative examples of the UVS observations during the Earth orbiting phase and the Mars transfer phase.
