Hi - recently I found a cheap source for red laser diodes with built in
power supplies. So - I was wondering - what kind of sensor should I use to
detect whether the laser was focused on that sensor? Hopefully something
that wouldn't be bothered much by other light sources. Better yet -
something that could handle high frequencies. Anyone have any
reccomendations? Thanks!
