Abstract: To calibrate a radiometric optical instrument by means of a light source, the focal plane of the optical instrument containing photoelectric detectors which convert image brightness into an electrical signal, the light source is disposed in the entrance pupil or in the aperture diaphragm of the instrument. The invention is particularly suitable for calibrating an optical instrument on board a satellite.
