矿物的反射光谱,是一种镜面反射光谱。它是指在一定的照明条件下,矿物的反射率随波长变化的特征曲线。 矿物反射光谱的某些光性特征已有人做了一些讨论。R·加洛平(Galopin)和N·F·M亨利(Henry)对铜蓝的光性随波长变化作了研究,陈正等还指出了反射光谱反映反射色,双反射和非均质性等光学性质。笔者认为,矿物的反射光谱具有特征的性质。虽然它是在单偏光下测定的,且仅为多波长反射率的连线,但它却统一地反映着矿物的绝大多数反射光学性质,包括单偏光下的全部光学性质和正交偏光下的许多重要光学性质。此外,还包含有矿物的结晶构造和化学成分两方面的综合信息。
The reflectance spectrum of minerals is a specular reflection spectrum. It refers to the characteristic curve of mineral reflectivity with wavelength under certain lighting conditions. Some of the photometric characteristics of mineral reflectance spectra have been discussed. Ropal Galopin and NFM Henry studied the photochromic behavior of copper blue as a function of wavelength. Chen et al. Also pointed out that the reflection spectrum reflects the reflected color, the double reflection and the heterogeneity Other optical properties. In my opinion, the reflectance spectrum of minerals has characteristic properties. Although it is measured under single polarization and is only a connection with multi-wavelength reflectivity, it reflects most of the reflective optical properties of minerals, including all optical properties under single polarization and orthogonal polarizations Many of the important optical properties. It also contains comprehensive information on both crystalline structure and chemical composition of minerals.
