For
25 years, there have been just a few basic effects available in laser
shows:
Abstracts
|
 |
Cartoon-like graphics
|
 |
Beams and fans
|
 |
Now, Pangolin is proud to present a new class of effect that has
never before been possible:
Photorealistic raster pictures
|
  |
This effect was invented by Pangolin and Lightspeed Design Group,
and it has been awarded an ILDA Technical Achievement Award. The
photo-illustration on the home page
symbolizes the process of turning a photo into raster scan lines,
which can then be projected by any standard laser show projector.
How raster frames work
Raster frames work very much like TV. Inside
the laser show projector, two small mirrors move the laser beam
in a scan pattern at high speed, while colors are derived from a
computer-controlled PCAOM crystal.
A TV tube only moves
electrons, not relatively massive mirrors. This means laser show
projectors must scan slower than TV. As a result, the
maximum laser resolution is about 60 pixels wide by 60 lines high, with
unlimited colors. Any photograph or video capture can be projected
at this quality. In fact, with
the program Lasershow Video model VST2002 (included with every LD2000 system), you can
even show live video!
Raster frames are usually
used as special effects within a laser show. For example, they can
simulate a TV or movie screen, or show the president of a company
during corporate presentations. By varying the raster, you can
create other special effects such as using a spiral or vertical
lines. Each LD2000 system comes with a free 4-minute show that
demonstrates all these effects and more.
