Abstract

The ECSEL joint undertaking RobustSENSE1 focuses on technologies and solutions for automated driving in adverse weather conditions. One of the main technology challenges is to improve laser scanner performance in fog where the existing 905 nm lidar reliability degrades below tolerances. This report briefly summarizes the results of experimental fog absorbance measurements, which were conducted in VTT icing wind tunnel located in VTT's premises. The content of the presentation will focus on spectral absorbance measurements in artificial fog in near infrared band.
