Abstract
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. The output of the pixel, formed by the output of the summing circuit of a last basic circuit of the pixel, supplies counting signals representative of the number of particles detected by the set of basic circuits of the pixel. Disabling certain basic circuits of the pixel, by selective zero resetting of the first input of their summing circuit, can enable only the particles detected by certain zones of the pixel to be counted.
