Abstract
A matrix of light-sensitive or x-ray sensitive sensors (S.sub.1,1, . . . S.sub.2000,200) are arranged in rows and columns and generate charges in dependence on the amount of incident radiation. The sensors comprise a respective electric switch (3) and are constructed, like the electric switches (3), of thin-film technology. Each sensor row has a switching line (5, 6, . . . , 7) via which the switches can be activated so that the charges of the relevant activated sensor row are simultaneously output via read lines (8, 9, . . . , 10, . . . ). Transfer means convert the signals read in parallel into a serial output signal; in order to achieve an as favorable as possible noise behavior. An amplifier (11, 12, . . . , 13) is in each read line and is constructed as a silicon crystal and precedes the transfer means. During the read operations, the amplifiers simplify the signals read from the sensors (S.sub.1.1, . . . S.sub.2000,2000) connected to the relevant read line (8, 9, . . . , 10, . . . ).
