美帝发射的火星飞船水手9号上装有两种红外探测仪器。一个是为了进行光谱试验的红外干涉光谱仪,通过试验可以测量由火星表面和大气所发射的辐射光谱亮度以获得大气和火星表面的参数,利用这些参数可以了解物理性能和火星表面成分及构造。通过试验还可测量大气垂直温度结构、大气成分及其动力学。由所得到的数据可以推导出水分的总含量、水汽的变化情况和测量大气的稀有成分。火星表面,包括极冠地区的温度、成分和热性能数值也可根据光谱推断出来。水手9号红外仪器所测量的光谱范围为200～1600厘米~(-1)(50～6微米),具有2.4厘米~(-1)宽光谱分辨率元件的空间分辨率,对1250公
USS Darter Mars spacecraft sailor on the 9th loaded with two kinds of infrared detection equipment. One is an infrared interference spectrometer designed for spectroscopy. By measuring the brightness of the radiation emitted by the surface of the Mars and the atmosphere, the parameters of the atmosphere and the surface of the Martian can be measured. These parameters can be used to understand the physical properties and composition and structure of the Martian surface. Through the test can also measure atmospheric vertical temperature structure, atmospheric composition and dynamics. From the data obtained, it is possible to derive the total moisture content, the changes in water vapor and the rare constituents of the atmosphere. The temperature, composition and thermal properties of Mars surfaces, including the polar regions, can also be inferred from the spectrum. The Mariner 9 infrared spectrometer measures a spectral range of 200 to 1600 cm -1 (50 to 6 μm) with a spatial resolution of 2.4 cm -1 wide spectral resolution component,
