the present invention relates to a multilinear charge transfer array having n rows of p detectors , each row successively receiving the radiation to be detected , an interface connecting the detectors to a group of charge transfer shift registers constituted by a first register with parallel inputs and series outputs having n × p stages separated into groups of n stages , in which each stage is connected to a detector of the same position of different rows , said register effecting the time delay and summation of the information and by a second register with parallel inputs and series outputs with n × p stages , communicating with the first register every n stages , the second register transferring the summated charges to a reading stage giving at the output solely a signal corresponding to the sum of the information collected on the detectors occupying the same position on the various rows .
