Abstract

Autonomous driving enable more use of in-vehicle interior lighting effects using advanced interior materials for illumination. Targeting premium visual ergonomics requires additional know how of today’s and future materials regarding light scattering. Within the presented work, we improved a goniophotometer towards a 2 standard deviation of < 0.08 %. This is in the range of a suitable limit so we successfully measured light scattering in terms of BSDF and/or BTDF of wood, transparent plastic (including 3D printed), and leather. These materials scatter light differently, so the results enable the base for optical simulation tools to design special visual effects.
