How do you align an array of hundreds of mirrors to a single spot with four photodiodes?
- mirimir 7y agoJust align one mirror at a time. The one being aligned vibrates at some frequency, and detectors around the target just measure that modulated signal. So just keep cycling through all the mirrors.
