Abstract
A method and a device are provided for reading a matrix of photonic detectors which delivers a current whose intensity varies according to the incident flux. A set of elementary points (PEL(i,j)) enables the signals delivered by each detector to be read. The quantity processed is the charge. Each elementary point effects a preintegration of the current delivered by a corresponding detector. A charge amplifier effects a reading to condition the signals delivered by the matrix of detectors and to multiplex them to at least one information processing chain.
