Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
The sort of sponsored bollocks that passes for science reporting in the Daily Mail makes the front page of Slashdot. I know the front page of Slashdot isn't run by the world's most incisive editing team, but come on!
That's what makes it special.
Laser projector? How can you project a raster image using a inherently vector system?
I don't get it. How does it know how big the pixels should be?
(Or maybe it's obvious and I just need a beating with the clue stick here)
The light from the three RGB lasers is scanned in rows just like the electron beam in a CRT. To sweep the angle, a tiny mirror flexes very fast. The technical challenge for these projectors has been switching the mirror fast enough and getting decent performance from miniature red green and blue lasers. I think the blue one was the tough nut to crack.
