spectral reflectance
spectral reflection
Examples
- Design of spectral reflectance measuring system
原位光谱反射比测量系统设计 - Canoy spectral refectance
天幕光谱反射比 - In optical character recognition , the spectral appearance of the image dependent upon the spectral reflectance of the image , the spectral response of the observer , and the spectral composition of incident light
在光学字符识别中,图象的光谱显现,它取决于图象的光谱反射系数、观察者的光谱响应和入射光线的光谱成分。 - For floodlighting , the luminance and the color of the lighted object depend not only on the power and the color of the illuminant , but also on the color of the lighted object ( the spectral reflectance of the surface ) , so , if we choose the optimum matching illuminant for the lighted object in lighting design , we can get excellence and energy efficiency result
摘要：泛光照明中,被照体的亮度大小、颜色变化等视觉效果不但与电光源的功率和光色有关,而且还与物体色(即光谱反射比)等有关,所以在进行照明设计时,应选择光源色和物体色相匹配的光源,这样才有可能使泛光照明效果较好,而且达到照明节能的目的。 - And the exponent relation between water content and soil spectrum are demonstrated , then the function of water content and soil spectrum are put forwarded , and the curve of absorption coefficient of water content in soil measured . basing the study on the course of reflection and scattering taking place on soil surface , a function of relation between soil spectrum and the roughness of clod was put forwarded . then a mathematic model on the relation between soil spectrum and water content and surface roughness are proposed
为建立象元组分信息模型，本文对土壤光谱与土壤含水量及表面粗糙度的关系进行了深入研究，论证了含水量与土壤光谱呈指数关系，提出了土壤含水量与土壤光谱的函数关系式，并测定了土壤水吸收系数；在研究土壤光谱反射与散射过程基础上，提出了土块级土壤粗糙度与土壤光谱的函数关系式，进而提出了湿润、粗糙土壤反射率的数学模型，并通过实验证明了模型具有较高的精度。
