Intelligent luminaires use plane mirrors at the front of the luminaire, mounted on a universal axis. Two small motors rotate the mirror in
pan
and
tilt
movement, causing the reflected
beam
of light to move on the stage.

Another use of plane reflectors in theatre is when, due to limited lighting positions, a scenic
projector
cannot generate the desired
projection
angle and size. A plane
reflector
can be used to reflect the
image
to the desired location on stage, and the distance between the
projector
and the mirror can be changed to manipulate the size of the image. |
