It's to what degree it sees it.  If the line does not occupy the entire FOV
of the sensor the amplitude is degraded.

An example of "not entirely" seeing something is if the line is occupying
only %50 of a sensors FOV.  That is "not entirely" seeing the line with that
one sensor, and as I said, amplitude is degraded in that case.

Well, the fact is, when sampling audio, the odds are that the Nyquist sample
rate (or anything but an infinite sample rate for that matter) won't catch
the full amplitude of the signal, it only "sees" the voltage when in time
the sample was taken, and it could be anywhere in the entire signal.

Who said there were?
