Patent number: 7652260Abstract: The particle detection circuit comprises a plurality of basic circuits. Each basic circuit comprises a particle detector element connected to an associated counter and a summing circuit having a first input connected to the output of the counter. Basic circuits, each forming a subpixel, are grouped together by series connection of their summing circuits to form a pixel.
