Spectral attenuation in low visibility artificial fog: Experimental study and comparison to literature models

The ECSEL joint undertaking RobustSENSE 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 test laboratories located in VTT's premises. The content of the presentation will focus on spectral absorbance at low visibility artificial fog in near infrared band.
