A question not about how to create a laser show, but how to re-create one of the world's most famous physics experiments of all time.
My RGB LP hasn't arrived yet, so I am left to killing time by learning LSX, browsing fabric stores, and dreaming of my first experiements to run when it finally does arrive...
Anyway, the infamous double slit experiement (Young's Experiement), has always fascinated me to no end, and one of the many reasons why I became interested in lasers to begin with - well that and the 12 years spent mingling in the 90's San Francisco music scene...
Anyway, I imagine it's fairly easy to do a simple double slit interference test - with a photon beam - you just have to get the slits the right width and the right distance from the laser - the hard part comes in lowering the intensity enough so that you can pretty much guarantee that single photons are firing from the laser.
The question is, is this possible with the analog modulation boards used in our projectors? Is there a DIY method for measuring photon reception at the receiving end?
There is a company called TeachSpin - that sells a complete single photon interference apparatus - I beleive it is around $7k... But how much fun is it to buy a ready-made apparatus?
Anyone ever experimented around in this area?
