Abstract
There is provided a digital light projection apparatus for projecting digitally selected light beams onto a stage display to create the effect of a continuously moving image. The apparatus has a fixed housing with a luminaire and a deformable micromirror device and a rotatable housing with a fixed mirror and a rotatable mirror. The deformable micromirror device directs selected light beams generated by the luminaire to the fixed and rotatable mirrors for projection to a stage display. Color may be achieved by use of color wheels, chromatic prisms, and/or lasers.
