摘要： A method for reading an imaging device intended for capturing images in a detector including a large number of photosensitive points called pixels organized into a matrix. The pixels of the same column are linked to a column conductor enabling the successive reading of the photosignals acquired by the pixels of the column, the method consisting for each of the pixels in carrying out a correlated double sampling read phase, the read phase comprising an operation of resetting the pixel followed by two read operations, the first without the photosignal, and the second with the photosignal. Three steps are concatenated in succession for the pixels of the same column: 1. a first of the operations of reading the pixel of a first row, 2. one of the operations of reading a second row, 3. a second of the operations of reading the pixel of the first row.

摘要： A digital detector includes a conversion block intended to convert incident radiation into electric charge; an electronic card that converts the electric charge into a digital image, the conversion block comprising N conversion stages superposed on one another, N being an integer between 2 and M, each of the N conversion stages comprising: a monolithic substrate; a first converter assembly in the form of a polygonal matrix array, M being the number of sides of the polygonal matrix array, M preferably being equal to 4, and configured so as to generate the electric charge on the basis of the incident radiation; an addressing and driving module for addressing and driving the matrix array, the addressing and driving module being arranged on the monolithic substrate along one side of the polygonal matrix array; each of the N conversion stages being oriented by at least 1/M of a turn with respect to the other N−1 conversion stages of the conversion block, and with an orientation distinct from the other N−1 conversion stages of the conversion block.

摘要： A photosensitive sensor includes multiple elementary sensors butted together, each elementary sensor comprising a pixel matrix organized in rows, the pixels of each row being connected to conductors of multiple types, column conductors of which are connected to read circuits of the sensor. The sensor moreover comprises, connected to each of the column conductors, a group of components that is separate from the conductor under consideration, the group of components forming a matching impedance of the conductor under consideration. The impedances in each elementary sensor have the same value and the impedances for different elementary sensors have different impedance values so as to balance the link impedances between the various read circuits and the corresponding column conductors for the various elementary sensors.

摘要： A matrix-array detector includes a set of pixels that are sensitive to a physical effect and arranged in a matrix array in at least one row and columns, each pixel generating a signal dependent on the physical effect, Q column conductors, each connecting the one or more pixels of one and the same column and intended to transport the signals generated by the pixels. The detector further comprises N multiplexers configured to operate simultaneously, each multiplexer receiving the signals from K column conductors, K being greater than or equal to 2, Q being at least equal to K2. The columns and associated conductors are ordered according to their physical distribution, q representing a current column. The N multiplexers are ordered from 1 to Q/K, n representing the rank of the current multiplexer. The column of rank q, where q is between 1 and K2, is connected to the multiplexer of rank n=q modulo K. Downstream of the multiplexers, the detector comprises a network of switches allowing signals present at the outputs of the multiplexers to be mixed.

摘要： An image detector comprises a sensor produced on a first monolithic substrate comprising a set of pixels organized in a matrix on rows and columns and configured to generate signals as a function of a radiation striking the detector, column conductors, each linking the pixels of a same column and intended to convey the signals generated by the pixels, at least one bump contact situated at the periphery of the first substrate and outside of the matrix of pixels and linked to the column conductors. At least two column conductors are connected together on the first substrate outside of the matrix of pixels and the column conductors connected together converge toward the at least one bump contact.
