Abstract
The invention relates to a head-up display device, including a projector for generating a light beam carrying information to be displayed, a combiner having a display position for displaying the information in the field of vision of a user, and an optical system defining an optical path between the projector and the combiner when the latter is in the display position thereof, for directing the light beam onto the combiner. The optical system includes a first and a second deflecting mirror. The first mirror is arranged for receiving the light beam from the projector and for sending said light beam to the second mirror, the latter being arranged for sending the light beam over the optical path toward the combiner. An actuation system is provided for adjusting the length of the optical path between the projector and the combiner by positioning the first and second deflecting mirrors.
