SCANNED-BEAM HEADS-UP DISPLAY AND RELATED SYSTEMS AND METHODS

摘要

A heads-up display that includes a scanner (46) and a projection assembly (54). 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. The device further comprises an exit pupil expander (52). 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 generate by a conventional display. Furthermore, one can often calibrate and recalibrate such a display withou physically modifying or replacing a component of the dsplay or of a vehicle incorporating the display.
