Abstract: An electronic addressing system to read matrices of optical-electronic elements, wherein the optical-electronic elements are of any type, for example photoresistors, photodiodes, light emitters, and the like. The matrices are bi-dimensional and comprise optical-electronic elements arranged according to a row-column structure, without any auxiliary switching an/or commutating means connected therewith. One end of each one of the elements is connected with a corresponding row near each row-column crossover, and the other end is connected with the column related to the crossover. The switching of each one of the optical-electronic elements which is addressed for reading is obtained by an adaptive analog compensation technique, whereby only a single element is read out while all other elements are electrically isolated.
