Abstract: A device for reading out two-dimensional charge patterns contains a receiver matrix (consisting of elementary transducers arranged in rows and columns) and a switching matrix (consisting of a carrier plate and electronic components in chip form) which are arranged on the long side of the carrier plate which faces away from the receiver matrix. A switchable amplifier in chip form is assigned to each of the elementary transducers connecting lines of at least approximately the same length are provided between contact lips and the corresponding switchable amplifiers, and signal output lines and ground lines run parallel to one another, while control lines run perpendicular to them. This design of the switching matrix makes the device unusually simple in its construction, with the amplifiers that are arranged on the long side of the carrier plate, which faces away from the receiver matrix, always being accessible, even after the device has been assembled. Thus, when individual image points drop out, the corresponding amplifiers can be replaced quickly and easily.
