A programmable light beam shape altering device using programmable micromirrors

摘要

A digital micromirror device ("DMD") is used to alter the shape of light that is projected onto a stage. The DMD selectively reflects some light, thereby shaping the light that is projected onto the stage. The light shape alteration is controlled by device that determines the shape of a performer on the stage and alters the shape of projected light to substantially conform with the shape of the performer.
