1. an interaction optical system, is characterized in that, an integrated infrared illuminator, and described infrared illuminator and described projection optical system share projecting optical engine light path;

  • Described interaction optical system specifically comprises three primary light source and illumination path thereof;

    Infrared light supply and illumination path thereof;

    Light valve;

    The even light shaping illumination path of compound eye;

    Illumination imaging light splitting combined prism;

    Three dichroic coated glass sheets and from axial projection'"'"'s imaging lens;

    Wherein;

    The even light shaping illumination path of described compound eye combines formed light path by plus lens group and fly'"'"'s-eye lens, for the inhomogeneous hot spot of the circle that enters described fly'"'"'s-eye lens being converted to the rectangular uniform light spots at light valve place;

    Described dichroic coated glass sheet, for three primary colours illumination path and infrared illumination light path is overlapping, is formed on the coaxial evenly rectangular illumination hot spot at light valve place;

    Described illumination imaging light splitting combined prism, for separating of illumination path and imaging optical path;

    Described from axial projection'"'"'s imaging lens, for the infrared illumination on projection screen is overlapped with the projected picture of visible ray.
