A Study of Specular Reflected Light in Goniophotometric Distribution Curve

Abstract

It is considered that the reflected light of the surface made from dielectrics is obtained by summation of specular reflected light component and diffuse reflected light component.
This paper describes the optical reflected characteristics of surfaces (i, e., a method of separation of the two reflected light components) made from dielectrics, such as papers and fabrics which are widely used in illuminating engineering.
The reflected light distribution curves are affected by roughness of the surfaces.
In this paper, we proposed a method of separation of the two reflected light components using polarized light, in consideration of roughness of the surface and characteristic of specular reflected light.
