I could be wrong but my thinking is if I reflect the sun from a 1 sq. in. mirror on a 576 sq. in. surface and the scan of the full surface takes 1 second, the bush will have received 1/576 of the sunlight during that second and yes that is really small but if I increase the scan frequency, it will increase the sunlight reflected on that surface. The question is, how fast can I scan the surface? perhaps step motors or servos are not fast enough. I would think increasing the scan frequency by about 200 times so in this example, the surface would get over 30% of the sun. Does this makes sense? or I am in the bushes...
