What is a Laser Projector?

The mental pictures that come to mind when one mentions the words “laser
projector” may differ substantially. Ones own initial idea might be that it
was similar to a small, standard DLP projector that is connected to your
notebook to do PowerPoint presentations. Others might envision a laser
pointer bouncing a beam off a small front surface mirror attached to the
voice coil of a speaker to generate an inexpensive display on the
wall.Still other people might think of the huge projector used in operation
at the IMAX theatres all over the world.

The laser projector I have designed is a small moveable device that hooks
up to your computer (via a dedicated laser contoller card) using a standard
25 pin RS-232 cable. The projector uses one to three lasers as light
sources to produce monochrome, or full color imagery. The projector
includes a means of specifically deflecting the laser beams, and furnishing
blanking when needed for images and text. The laser beam deflection is done
by the usage of 2 closed loop galvanometers that have front surface mirrors
attached to the ends of the rotary shafts of the motors.The blanking is
done by directly modulating the lasers. The last thing you need is to add a
small portable sound system for the music that inspired the laser shows you
will play.

The laser projector can project graphic animations and/or beams of laser
light all synchronized to the music. A laser projector could be used to
project images seen in broad daylight (a very powerful one) but is best
viewed in total darkness for maximum dramatic effect. A laser projector
could cost you anywhere from under a $1000 to tens of thousands depending
upon your budget and requirements. I have designed and buil many laser
projectors over 10 years beginning with Acousto-optics modulators for
blanking huge power hungry argon/krypton lasers. I then moved to using
polychromatic AOM’s for blanking which made life much easier but still had
to lug around monster lasers that needed water cooling and lots of TLC. I
eventually moved on to solid state lasers that are easy for one person to
transport and do not need water cooling or high power demands to function.

I can run my entire system from a single 120 VAC wall plug. What a
difference… If you have a laser based project but don’t have the time or
skills to make your Idea come to life I’m available to provide my R & D
skills and make your dream a reality.

I’ve been working with lasers for over 20 years. I’ve been designing,
building and operating laser projectors over 10 years. As a laser operator
or Laserist I enjoy another avenue for creative expression using this
amazing media to help charities of my choosing.
