Iridescent colors of optical disks are caused by light diffraction from their surface microstructure. This paper proposes a diffractive illumination model for optical disks based on their physical structure and the superposition principle of light waves. This model includes contributions due to diffractive and non-diffractive factors. For the diffractive part, we first model the pit periodicity for optical disks by using identical spheres and then simplify their distribution by uniform groups… CONTINUE READING
