A system is provided for the high speed reading of an image formed on the CCD sensor where the useful zones are formed of bands parallel to one of the directions of the matrix, and separated from each other by a gap without useful video information, each band and each gap being formed of several scanning lines, the geometrical arrangement of the bands on the matrix being known beforehand. The lines of each gap are transferred in succession into the register and the corresponding noise signals are not taken into account. The lines of each band are also transferred in succession so as to provided, pixel by pixel, the video signals summated in analog form for the band considered. The system applies more particularly to multichannel recording systems with streak camera.

A system for the high speed reading of an optical matrix sensor with charge transfer organized with single stroke frame transfer for the video detection of brief images, in which the video information is distributed over the detection matrix in several parallel bands each having several lines of pixels, the remaining part of the detection matrix forming gaps of separation between these bands and being deprived of useful video information, each gap also having several lines of pixels, the geometric XY arrangement of the bands on the detection matrix being known beforehand, the sensor including said detection matrix and a reading register connected to a video output circuit, the reading of the matrix being controlled by an associated signal generator and providing, not only for each band but also for each gap, the parallel transfer of the lines forming the band or the gap considered before commanding the series reading of the contents integrated in said register, so as to allow reading at maximum speed of said gaps while controlling the elimination of the corresponding detected noise, as well as for directly obtaining in analog form the integration pixel by pixel of the useful video signals of the lines of each band.
