MATRIXDETEKTOR MIT LEITERN MIT GESTEUERTER IMPEDANZ

摘要

The present invention relates to a matrix detector comprising: • a set (10) of pixels sensitive to a physical phenomenon and organized in a matrix according to rows and columns, each pixel generating a signal depending on the physical phenomenon, • line conductors each allowing to control the pixels of a line, • control modules (16) delivering selection signals to the line conductors, the control modules (16) being configured to deliver signals according to two levels including a high level allowing selection of one of the pixel lines and a low level not allowing its selection. According to the invention, the detector further comprises impedance modules (22) connected to each of the line conductors and configured to lower the impedance of each line conductor and maintain each line conductor at low impedance, during a reading phase of the set (10) of pixels, as long as the corresponding selection signal is at the level low water, the impedance modules (22) being separated from the control modules (16).
