A method can include providing an optical device having a first surface, a second surface normal to the first surface, and a third surface arranged at an angle to the second surface. The third surface can be reflective to light of a first state and transmissive to light of a second state. An input beam having the first state can be normally incident on the first surface. A transmissive diffractive optical element on the first surface can convert the input beam into at least a first diffracted beam directed toward the third surface, where it is reflected by the third surface in a direction substantially parallel to the first surface. The reflected first diffracted beam can be modulated with image information using a spatial light modulator to produce a modulated light beam having the second state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Low-profile beam splitter","description":"Examples of light projector systems and methods of use.
