Laser Graffiti

March 26, 2010

Everyone check out this video:
The Optical Society student chapter at UCI made that (that’s me!). That’s use writing on the back of the science building…with LASERS!
So first of all: go watch that video, watch it a lot, and pass it around. We win prizes if it gets enough views.
Secondly: here’s how it works. You draw on a building with a laser pointer. A webcam sends the image of the building through some software that knows what to look for. Then a projector sends it back onto the building so the trace stays there.
Also: it’s totally awesome. Come visit me and you can play with it too!
