Abstract
A head-up display including a combiner and a relay optics formed from a combination of optical elements and forming an intermediate image projected to infinity by the combiner of a symbology emitted in a given spectral band by an image source. The combiner forms an off-axis convergent mirror in the spectral band, and an angle of inclination of the off-axis convergent mirror is adjustable for a given type of equipment as a function of a position of the image source and in a given angular range that depends on the type of equipment. The relay optics is modular and includes a first module with at least one optical element fixed regardless of the type of equipment and a second module with at least one optical element for which a position is predefined as a function of an angular position of the combiner.
