ABSTRACT:
Disclosed is a detection method and a corresponding array architecture comprising sensors positioned according to a particular geometry, enabling the integration of a circuit for the management of the integration cycles and of transfers of charges between injection-integration circuits and TDI type summation circuits in the focal plane of the array. The array is fitted into a scanning camera that scans in a particular direction. The camera is designed to form a video signal for an image made up of pixels spaced out at a pitch p.sub.p with a value corresponding to the standard. The array has several rows of elementary sensors. The the sensors that belong to different rows and are aligned in the scanning direction define a detection channel V.sub.k. The spatial pitch p.sub.c of one and the same detection channel has a value that differs from the value of the pixel pitch p.sub.p by a fraction of this pixel pitch such that a sensor-pixel coincidence, which is achieved for a reference sensor C.sub.0, is no longer synchronous for any other sensor exposed to the same elementary field of view.
