Well, we used one of those last year, but if anything gets in the way, a frisbee or a bot or even the pyramid, it will return a false distance. So I was thinking of going with the photon cannon idea and using the distance between the top and bottom retroreflective tape to give me my distance using some basic trig functions. I was just seeing if there were any very efficient algorithms on doing this. I don't want it to take up a ton of processing obviously.
