Abstract:
1. A device for detecting radiation consisting of particles or electromagnetic waves comprising at least one two-dimensional set of elementary sensors of semiconductor type for transforming energy of the radiation to be detected into electric signals, each of the elementary sensors being provided on one side with an anode and on an opposite side with a cathode, the anode and cathode being adapted to be electrically connected on a circuit for reading and operating on said signals, wherein: anodes of said sensors are electrically interconnected so as to constitute a plurality of anode subsets, said anode subsets being electrically connected at least in pairs to a measuring anode path, said path being looped on said reading and operating circuit, each anode is connected to two separate measuring anode paths, cathodes of said sensors are electrically interconnected so as to constitute a plurality of adjacent cathode subsets, each of said cathode subsets being electrically connected to a measuring cathode path, and the anodes belonging to two anode subsets and connected to a common anode path are associated with elementary sensors whereof the cathodes belong to separate cathode subsets.
