Abstract
A head-up display system includes an eye-box having a first and second dimension, an image projector including a picture generating unit and an optical system, and a movement assembly. The picture generating unit includes a spatial light modulator arranged to spatially modulate light in accordance with a hologram. The optical system relays the spatially modulated light to an optical combiner. The movement assembly moves at least a portion of the image projector rectilinearly between a plurality of positions such that at least one component of the picture generating unit is moved together with the optical system. Spatially modulated light relayed to the optical combiner forms a virtual image viewable from a sub-eye-box having a position in the first dimension being dependent on the position of the at least a portion of the image projector. The eye-box is the sum of the sub-eye-boxes associated with each of the plurality of positions.
