Abstract
A light display system for projecting digitally generated light beams onto a stage display, comprising a housing rotatable about at least one axis, a deformable mirror device (DMD) having a surface comprising an array of deformable mirror cells, the DMD being mounted in the housing, a light source mounted in the housing for directing a light beam in an optical path that impinges upon the surface of the DMD, and digital control signals to the DMD for digitally activating selected deformable mirror cells of the DMD to reflect digitally selected light beams onto the stage display having the optical effect of a continuous moving image or images. The housing is rotatable about a second axis transverse to the first axis. Coloring devices can be mounted in the housing.
