The invention relates to an image acquisition device comprising a sensor composed of an array of photosensitive pixels, and an array of elementary filters covering the sensor. Pixels may be of three different types: panchromatic pixels, primary colour pixels and infrared pixels. Under low illumination conditions, the device displays a monochrome image using panchromatic pixels, and under high illumination conditions, a colour image with a high signal to noise ratio, by combining primary colour images and subtracting the infrared image.

Device for acquiring bimodal images

An image intensifier tube and a night vision system fitted with such a tube. The tube body of the image intensifier tube includes a multilayer ceramic substrate fixed in a sealed manner to an input device and to an output device so as to assure leaktightness of a vacuum chamber delimited by the tube body. The multilayer substrate also maintains a microchannel plate arranged between a photocathode and a phosphorus screen, and supplies voltage to the photocathode, the plate, and the phosphorus screen.
