Perhaps one of you could answer this query for me -
given that an observer is a particular distance away from an object,
and focusing on that object, does the focal area a sphere which radiates in
three dimensions around the focal point have the same span in each dimension
around the point (i.e. is Z the same as X and Y).
Additionally, if the observer moves towards or away from the fixed object,
does the focal sphere size decrease exponentially with distance, or is there
some other relationship caused by the possibility of focusing the lens (i.e. is
there some sort of graph which would model this???).
What I am interested in is the resolution fluctuations which are predominant
in the human optical system, and how they are affected by various factors.
Any references welcome also,
Many Thanks,
