I want to build a projector, where a beam of light is shining on to mirrors, placed at different angles, which are spinning fast enough to draw lines. The question is, how to calculate the needed angles/distances/sizes to get the desired image output? Can anyone point in the right direction?
The goal is to get a line as shown in the top view. It needs to be N wide. In order to do that, I need to figure out how high the moving mirrors should be placed and at what angle. The same goes for the laser pointer. Also how big the mirrors should be.
