WebDichroic filter. A dichroic filter, thin-film filter, or interference filter is a color filter used to selectively pass light of a small range of colors while reflecting other colors. By comparison, dichroic mirrors and dichroic reflectors tend to be characterized by the colors of light that they reflect, rather than the colors they pass. WebThe dichromatic reflection was proposed to use the spectral projection in the color space with the diffuse and specular reflection colors as the boundary. However, this method required that the pixel on single surface should be in the parallelogram [9] .
