Scattered Light Predictions for Aluminum Painted Reflectors in Automotive Tail Lamps 2002-01-0913

Scatter analysis is essential in the optical modeling of diffuse reflectors in automotive tail lamps. Significant advances in scatter measurement and modeling have enabled accurate detection and simulation of diffusely reflected light. Scattered light predictions for reflectors coated with aluminum paint were made using Bi-directional Scatter Distribution Function (BSDF) measurements and ASAP™ optical modeling software. Correlation between the predicted and measured far-field light distribution is excellent, with a Pearson correlation factor of 0.981. The resulting scatter models for aluminum paint have been integrated into the optical design and analysis of diffuse reflectors in automotive tail lamps, improving the accuracy of the lamps predicted performance during product development.
