Matrix digital detector with dynamic noise adaptation

Abstract

Matrix detector for detecting electromagnetic radiation with dynamic noise adaptation, comprising a matrix of pixels which are sensitive to electromagnetic radiation and deliver an electrical signal the level of which depends on the intensity of the received electromagnetic radiation, the pixels being addressed in groups of at least one row, the detector being configured to: - operate at at least two different image acquisition frequencies, - determine, for all the frequencies, the maximum available time (LPML) for reading one of the groups of at least one row, - use, for each of the frequencies, the entirety of the maximum available time (LPML) to read the group.
