Abstract
In a method for measuring fine particulates in the vicinity of a motor vehicle with an optical receiving device, at least one LED () arranged inside the motor vehicle lights up an outside air region. The optical receiving device is designed to capture the area under examination in a spatially localized manner and takes an intensity measurement in an area that is lit by the LED. The intensities measured are analyzed for diffraction patterns that depend on the size of the fine particulates. Additionally, a portion of the light that is coupled into the windshield is also analyzed for the presence of water on the windshield.
