Three-dimensional internal back-projection system and method for using the same

An image projection system, comprising:

• a coherent light source configured to emit coherent light in a visible portion of the electromagnetic spectrum;
• a microdisplay array that receives the coherent light from said coherent light source and provides a controlled coherent light output representing an image;
• an optical lens assembly that operates on the coherent light output of said microdisplay array and delivers a corresponding coherent light output adapted for projection onto a variety of projection screen configurations without alteration of said optical lens assembly, said coherent light output as provided by the optical lens assembly being formed and adapted for casting an image using coherent light rays onto a surface of a projection screen while substantially retaining a sharpness of said image over the surface of said projection screen;
• said projection screen having a three-dimensional configuration substantially defining an enclosure volume through which the coherent light output from the optical lens assembly travels to be incident upon an inner surface of said screen;
• said projection screen being constituted to have an inner surface, an outer surface, and a composition there-between;
• and
• said projection screen and said composition being configured and arranged to receive the coherent light output from said optical lens assembly and to present said corresponding viewable image that is observable from outside the enclosure volume.
