I am trying to piece together how the parabolic mirror manages to reflect the "red dot" from the focal point to the eye without distortion.
I compare this with a conventional car headlight, which operates almost exactly the same way, except it has a non-transparent backing. Why does the ret dot scope manage to produce a clear image of the "dot" (focal point), whereas the car headlight apparently distributes the light evenly throughout the surface?
In other words; they have the same design, but when you look at the car headlight (perhaps with sunglasses on), you will not see the light focused in a point. It will appear as if the whole paraboloid surface is shining (no "dot").
Does anyone here care to shine some light on this? :)
(I hope you appreciate the my engineering humor).
