Sensormatrix

Abstract

Abstract In an arrangement with a matrix of photosensitive or X-ray sensitive sensors (S1,1 ... S2000,2000) disposed in lines and columns, which generate charges dependent on the level of incident radiation, which in each case have an electrical switch (3) and which, similar to the electrical switches (3), are produced in thin-film technology, with a switching line (5, 6, ..., 7) for each sensor line, via which the switches can be re-activated so that the charges of the respectively activated sensor line discharge simultaneously via read-out lines (8, 9, ..., 10, ...), and with transmission means for conversion of the signals read out in parallel into a serial signal, in order to obtain an optimum noise response, an amplifier (11, 12, ..., 13) manufactured in silicon crystal technology is provided in each read-out line (8, 9, ..., 10, ...) which is connected upstream of the transmission means and which, during the read-out of the sensors (S1,1 ... S2000,2000) which are connected to the respective read-out line (8, 9, ..., 10, ...) amplifies the sensor signals which have been read out. <IMAGE>
