<p>A representative embodiment of the invention provides a compact image projector having a light source coupled to a spatial light modulator (SLM). The light source has a substantially planar structure. The overall size of the SLM is dominated by its length and/or width. The projector has an optical arrangement that enables the SLM to be oriented so that the SLM' s dominant dimensions are parallel to the plane of the light source. Due to this relative orientation of the SLM and light source, one of the dimensions of the image projector can be smaller than 12 mm, which advantageously enables incorporation of the projector into a hand-held electronic device, such as a cell phone, PDA, or media player.</p> |
