| Title: |
Laser Projection System and Safety Lens for Audience Scanning |
| Abstract: |
A laser light projector includes a laser beam generated by a laser light
source, a scanner associated with the laser light source and having one
or more moving mirrors capable of scanning the laser beam along X-Y
coordinates, a scan-fail monitor and a safety-lens. The safety-lens
includes a plurality of powers arranged for increasing the safety of the
projected light within audience areas by increasing beam divergence in
the audience, while keeping beam divergence low above the heads of the
audience, thus allowing mirror targeting to occur.
