The simulated light distribution for each individual source pixel is used during the driving simulation. The masked region shown on the aiming wall is not entirely dark anymore. Instead, you can see some illumination caused by Fresnel reflections, aberrations, stray light effects, ghost images from your optical system, impact of coatings, etc. | 草榴社区

LucidDrive recently introduced a sensor capability that makes it possible to assess the illumination quantitatively now also during or after a driving simulation. Here, various sensors are recording the illumination of the respective sensors over time. This is done to assess glare for the FMVSS 108 ADB test. | 草榴社区
