4 Thick black lines are walls. Mirrors only have a reflective coating on one (blue) side. The grey grid is only for orientation. The detectors work for any incidence angle."> You have a setup like in the image above. But it seems like detector A does some weird things. You should better check it with detector B . What is the minimum number of mirrors you have to move (translate and rotate arbitrarily) to bring the laser beam onto detector B ? Please leave the mirrors which are used to direct the laser to detector A as they are, because if it turns out detector A is not broken you want to switch back to it. I mean it's quite well shielded from stray light compared to detector B . The thick black lines are walls. Please don't burn any holes in them. The mirrors all look the same. They ha...
