MATRIX DETECTOR WITH REDUCED ODD/EVEN EFFECT

摘要

The invention relates to a matrix detector comprising: - a set of pixels arranged in a matrix according to lines (L) and columns, each pixel (P) being suitable for generating a signal depending on a physical phenomenon, - a signal generator (GSI) configured to generate two clock signals (CK1, CK 2) phase-shifted with respect to one another, - a device for addressing the lines comprising a shift register (SR), the shift register (SR) comprising a plurality of stages (ET) arranged in cascade, each stage (ET) being capable of receiving, alternately from one stage to another, a clock signal from the two clock signals (CK1, CK2), and being capable of issuing an intermediate output signal (OUTn), which can assume a high level (Von) and a low level (Voff), enabling activation and deactivation respectively of the pixels in the line, characterised in that the signal generator (GSI) is also configured to generate a third clock signal (CK3), the addressing device also comprising a plurality of isolation circuits (ISL), each isolation circuit (ISL) being connected between each stage (ET) and the corresponding line (LI) of the matrix, and configured to receive the third clock signal (CK3), the isolation circuit (ISL) being configured to issue a select signal (OUT_LINE_n) selecting the corresponding line of the matrix when the intermediate output signal (OUTn) and the third clock signal (CK3) are at a high level (Von).
