In one embodiment, a geometrical relationship exists between the cover glass and the pixel mirrors, such that light that reflects from the cover glass is separated from light that reflects from the pixel mirrors and is transmitted from the SLM. In one example, one of the cover glass or the pixel mirrors is angled with respect to the modulation layer. In another example embodiment, the cover glass has a particular thickness, which introduces destructive interference between light that reflects from the top and bottom surfaces of the cover glass. In another embodiment antireflective coatings are disposed between optical interfaces of the SLM. In another embodiment, light from the SLM is directed through an optical filter to remove unwanted light."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Spatial light modulator for reduction of certain order light","description":"A novel spatial light modulator (SLM) includes a cover glass, and modulation layer, and a plurality of pixel mirrors, and separates unwanted, reflected light from desired, modulated light.
