Abstract
A device and a method of digitalisation for at least one photosensitive detector (DET(i,j)), which supplies a current, the intensity of which varies in relation to the incident flux, and a method for reading a matrix of photonic detectors. The device includes an assembly of elementary points (PEL(i,j)) which enables the signals supplied by each detector to be read. The quantity processed is the charge, each elementary point carrying out a preintegration of the current supplied by a corresponding detector and at least one information processing chain, including a regeneration device which carries out a reading of the resultant charge quantity in the form of a current pulse so as to package the signals supplied by the detectors; the signals coming from the processing chain(s) being multiplexed to at least one digital output.
