Patent ID: 7672506

Claim:
A system for spatial analysis of a physical quantity whose spatial values (S 1 to Sn) are respectively represented by measurement pulses (I 1 to In) whose order in time is representative of those values, said system comprising a plurality of processing units (U 1 to Un; p n ) for processing said measurement pulses, said processing units being arranged in one or more rows and each having an output (SOR 1 to SORn) at which, during successive processing cycles, a measurement pulse that is processed therein is delivered to form an output signal (SU) of said system, wherein each of said processing units (U 1 to Un; p n ) further includes an inhibition unit (BI) for inhibiting, in other units of said one or more rows and during a processing cycle, passage toward the outputs (SOR 1 to SORn) of those other units of respective measurement pulses that are processed therein, and thereby preventing said respective measurement pulses from forming said output signal (SU) of the system, if those measurement pulses are ordered later in the processing cycle concerned than the pulse processed in the unit concerned.
