Abstract:
A light display system for projecting digitally generated light is onto a stage display, comprising:a housing rotatable about at least a first axis and a second axis; said second axis transverse to said at least first axis; said first and said second axes are respectively a horizontal axis and a vertical axis; a deformable micromirror device having a surface comprising an array of deformable mirror cells, said deformable mirror device being mounted in said housing; a light source means mounted in said housing for directing a light beam in an optical path that impinges upon said surface of said deformable mirror device; digital signal means for providing digital control signals to said deformable micromirror device for activating selected deformable mirror cells of said deformable micromirror device to reflect image-forming digitized light beams onto the stage display; said housing including first means for rotating said housing about said vertical axis and a second means for rotating said housing about said horizontal axis; said first means for rotating said housing about said vertical axis a first driver securable to a fixed structure and operatively connected to said housing and said second means for rotating said housing about said horizontal axis is a second driver operatively supportable by said fixed structure and operatively connected to said housing; a housing movement computer means connected to said first and second drivers for rotating said housing in a predetermined sequence of combined horizontal and vertical movements; and said predetermined sequence of combined horizontal and vertical movements are synchronized in predetermined timed and spatial sequences with said digitally generated light beams being reflected from said deformable mirror device and directed onto the stage display.
