1. An apparatus for displaying three-dimensional projected images on a distant screen comprising:

  • first means for receiving a first sequency of light beams and for selectively changing the polarization orientation of linearly polarized light incident thereon in response to said first sequence of light beams;

    second means for receiving a second sequence of light beams and for selectively changing the polarization orientation of linearly polarized light incident thereon in response to said second sequence of light beams;

    first writing means, operably connected to said first means fore receiving, for selectively generating said first sequence of light beams;

    second writing means, operably connected to said second means for receiving, for selectively generating said second sequence of light beams; and

    means disposed for projecting a high intensity light beam onto said first and second means for receiving;

    said first and second means for receiving and said means disposed for projecting being positioned with respect to each other such that light reflected from said first means for receiving does not impinge upon said second means for receiving and such that light reflected from said second means for receiving does not impinge upon said first means for receiving.
