ABSTRACT:
A heads-up display that includes a scanner and a projection assembly. The scanner generates an image by sweeping a beam of electromagnetic energy, and the projection assembly directs the image into a predetermined viewing space having a region with a substantially uniform intensity profile. Such a heads-up display can often be made smaller than a conventional heads-up display, and can often generate an image having a higher quality than an image generated by a conventional display. Furthermore, one can often calibrate and recalibrate such a display without physically modifying or replacing a component of the display or of a vehicle incorporating the display.
