Does anybody have a good way to understand this?
=========
There are a lot of good ways to understand this. The amplitudes
determines how much
to put, while the phases tell you where to/how to correctly put. For
example, treating San
Francisco as a cell, the heights of buildings and lines of streets
determine the landscape.
Moving all buildings along some streets separately will change more
the landscape than
just changing some buildings' height along the street. Another
example, taken at different
lighting/darkness conditions, the photos from the same face could be
easily recognized
and compared. However, with the same light condition, when the
position of nose, eyes,
mouth, etc., are dislocated from their original positions, the face
will be very different.
One possible answer is "it is the nature of the Fourier Synthesis to
emphasize phases." (Which is a pretty unsatisfying answer). But,
could there
be an alternative summation which emphasizes amplitudes? If so, that
might
be handy in our field, where we measure amplitudes...
==========
It does have. For example, Patterson function.
