Abstract
A particle detector apparatus for optically ascertaining a number of particles arranged on a surface of, for example, a particle filter. The particle detector apparatus includes a light source, an optical focusing device, a spatially resolving light detector and an evaluation device. The light source emits source light onto the surface. The optical focusing device focuses image light that is emitted from the surface in response to the source light onto the spatially resolving light detector. The spatially resolving light detector includes light sensors that measure brightness values based on the image light, such that the light detector produces image data based on the brightness values delivered by the light sensors. The evaluation device then ascertains the number of particles based on the image data.
