Claim Text:
1. A method for creating multiple different heads-up display images at different apparent distances from a viewer, comprising: generating a first image using a first subset of modulating elements of an array of image pixel modulating elements of a spatial light modulator; generating a second image using a second subset of modulating elements of the array of image pixel modulating elements of the spatial light modulator, the second subset of modulating elements separated from the first subset of modulating elements, such that the second image is separately generated from the first image; directing light from the first image along a first optical path onto a transparent display surface to form a first virtual image at a first apparent distance within a field of view of a viewer looking through the display surface; directing light from the second image along a second optical path, shorter than the first optical path, onto the transparent display surface to form a second virtual image at a second apparent distance within the field of view of the viewer looking through the display surface.
