1. A method, comprising:
- sweeping a beam having a profile in a cross section;
converting the profile of the beam into substantially a spatial sinc function;
performing a spatial Fourier Transform on the spatial sinc function to generate an image; and
directing the image into a predetermined viewing space with a wind screen of a vehicle.

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.
