Abstract: An electromagnetic wave detector having a first detector element including an active photoconducting material capable of detecting a band of wavelength and a second detector element including an active photoconducting material capable of detecting the same band of wavelength. A common layer is positioned between the first and second detector elements. A first and second connectors are configured to connect to the first and second detector elements, respectively. A third connector is configured to connect in common to the first and second detector elements. The detector further includes contact mechanisms configured to apply control voltages where the voltage applied to the third connector has a value between the values applied to the first and second connectors. A reading circuit connected to the third connector reads a photoconduction current difference between the first and the second detector elements.

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.
