Alignment system

Abstract:

An alignment system comprises a first diffractive optical element comprising an image and a laser source. The image is visible when the laser source is viewed from a desired field of view through the diffractive optical element. The laser source may be configured to produce a beam of light that will extend through at least a portion of the first diffractive optical element, thereby illuminating the image. The first diffractive optical element and the laser source may be disposed in a vehicle.
