| Title: |
Two-Axis Beam Steering System for Use in Automated Light Fixtures |
| Abstract: |
A beam steering mechanism for deflecting a light beam along any selected
azimuth and elevational direction. The beam is movable without limitation
about a pan axis and about a tilt axis, by drive motors that are rigidly
mounted to a housing and are not bodily moved with the light beam.
Movement about the pan axis is effected by rotation of a first mirror
mounted in a first rotatable cylinder. Movement about the tilt axis is
effected by rotation of a second mirror mounted in a second cylinder that
is panned with the first cylinder and is itself mounted for rotation about
the tilt axis.
