Abstract
In a device photosensitive to infra-red radiation each infra-red detector is associated with means enabling the injection into a semiconductor substrate of a quantity of charges representing a function of the infra-red radiation received by the detector, and with means assuring the storage of these charges. The storage means of the detectors of one and the same line are joined via connections to charge reading means, common to the detectors of one and the same line, and which assure the column after column reading of the detectors by reason of a shift register which successively addresses the storage means of the detectors of one and the same column. The device as a whole may be integrated within a cryostat having a single high-level output.
