A non-telecentric display system that prevents ghost images includes an optical waveguide and a display engine. An image former of the display engine includes a reflective surface having a surface normal thereto. An illumination engine of the display engine emits light towards the reflective surface of the image former such that chief rays are offset by acute angles from the surface normal to the reflective surface. The display engine directs light corresponding to an image, that reflects off the reflective surface of the image former, towards an input-coupler of the optical waveguide so light corresponding to the image is coupled therein and travels by total internal reflection to an output-coupler of the waveguide. Ghost images are prevented at least in part due to the chief rays of light emitted by the illumination engine being offset by acute angles from the surface normal to the reflective surface.
