In an optical device for the display of light data collimated to infinity, an image generator associated with a collimation optical device gives the eye an image collimated to infinity. The light source that illuminates the image generator is controlled so that the position of its illuminating part is such that it gives a narrow beam with an image of this illuminating part centered on the pupil of the eye. This is possible by means of an oculometer that determines the coordinates of the center of the pupil of the eye and delivers a signal enabling an automatic control circuit to adjust the position of the illuminating part of the source accordingly. The device can be applied to pilots' helmets for the display of data overlaid on the landscape.
