The smoother the surface is, the more specular the reflection. On a very smooth surface, lines normal to neighboring points along that surface are parallel to each other. Since the angle of reflection* depends

Diffuse reflectance spectroscopy is a well-established technique for studying the spectral characteristics of opaque solid samples, based on the principle that not only does light reflected from the material come from the surface (specular reflection) but some is reflected internally (diffuse reflect...

由于在Lambert反射下,各方向的Excitant Radiance是相同的,因此可以用这个值计算出Excitant Radiance的值,也就是Lambert Reflection的BRDF: BRDFd=1πDcoeffBRDFd=1πDcoeff 与之对应的还有,而Specular Coefficient,它和方向有关。Diffuse Coefficient和Specular Coefficient加起来,才等于Albedo。
Mixed diffuse and specular reflection boundary conditions are applied along the ratchet surface. Based on kinetic theory, an analytical solution has been found for the net force between the walls in the free molecular flow regime. A significant gas mass flux along the channel has been demonstrated...

While specular light is reflected only at 90°, diffuse light is reflected over a wide range of angles, including the specular angle. The specular reflection, which is sensitive to the area covered by the toner is used to control the Tone Reproduction Curve (TRC), and hence the colors print...
Such behavior is in good agreement with the experiment and mainly determined by specular reflection at the conical part of the crystal (its shoulder) while the effect of specular reflectivity of the cylindrical part and melt-free surface is significantly less. It is also shown that radiation ...
