| Title: |
Programmable Light Beam Shape Altering Device Using Programmable Micromirrors |
| Abstract: |
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 control
for the alteration is controlled by an image. That image can be
processed, thereby carrying out image processing effects on the shape of
the light that is displayed. One preferred application follows the shape
of the performer and illuminates the performer using a shape that
adaptively follows the performer's image. This results in a shadowless
follow spot.
