Colorimetric properties of the light scattered by various objects [PDF]

open access: yesSPIE Proceedings, 2004
The artificial reproduction of some coloration effects (for instance nacre aspect, iridescence) which appear spontaneously in the nature needs a right description of the different mechanisms which are involved in these phenomena and especially, a detailed analysis of the spectral behavior of the light scattered by such surfaces. With this aim in sight,
