Abstract
(EN)
An imaging system comprising circuitry configured to obtain (S2) image data of a scene that is illuminated with patterned light (PL), determine (S5, S6) bright regions and dark regions based on the image data, and relate image information related to the bright regions to image information related to the dark regions in order to determine characteristics of atmospheric aerosol particles (AP).
