    摘要: Multiple image projection apparatus are described. A cubic multi-prism beam splitter is provided having diagonal interfaces with one or more PBS elements and/or reflective elements positioned thereon. At least first and second spatial light modulators, such as LCoS SLMs, are positioned adjacent the beam splitter cube. The first and second LCoS spatial light modulators and first and second projection optics systems are configured to output a first modulated image from the first LCoS SLM to the first projection optics system and a second modulated image from the second LCoS spatial light modulator to the second projection optics system. In other embodiments, additional LCoS spatial light modulators and light sources produce 3-D images. Addition of sensors permits user interaction with a projected image which is fed back to a controller to optionally change current or future images displayed by the system.
