I was pretty surprised , nae shocked to see wikipedia does not have section related specificlly to laser projectors , as best i can find anyway.
So ... i started one .. very basic , just a few words to get it going .... as i know the greater knowledge on here will fill it full of useful information in due course .......
http://en.wikipedia.org/wiki/Laser_projectors
For anyone who does not know , wikipedia can be edited by anyone at anytime ..without even logging in ...so dont spend a day writing a tomb as some 12 year old know it all will come along at some point and overwrite your conidered words with nonsense ..dont expect what you write to be there in a year ..these articles go though many hundreds of revisions , until eventually when a mod think its comprehensive enough it gets locked but that could take many years.
I havent spent much time on wiki, if you have ,could someone make up the little menu that breaks it into sections ,i think that will make it easier for contributions
Have fun
