Abstract
A system for the conversion of an infrared image into a visible or near infrared image includes optical input and output devices, an infrared detector on which is formed an infrared image of a scene, a circuit for reading the signal supplied by the detector, a circuit for processing the signals from the reading circuit, a visible or near infrared light emitter for supplying the image in the form of visible or near infrared light from signals of the processing circuit, a circuit for addressing the emitter, and a substrate. One face of the substrate forms a focal plane common to the optical input and output devices. The detector, the reading, processing, and addressing circuits, as well as the emitter, are integrated in this focal plane.
