Resampling Points in X Details
Maximum resolution between
real points is at near FOV
(without resampling)
Distance
between real
points is larger at
the far FOV
(without
resampling)
The rectified output Z-points
are an interpolation
between the closest left and
right real pixel

uniform spacing in X
Additional interpolated X points are dependent on the step size
Since FOV width is fixed, the X step size determines:
- distance between output points in microns
- number of output points
If the number of output points (set by Z-Trak2, not by the user) is greater than the
number of real points (dependent on the step size), those new points are created
by interpolation between real points.

Resampled Z-points are calculated based on adjacent real points.

Possibility of Invalid Interpolated Points
If there is an invalid point between valid real points, all interpolated points created
between the two valid real points are also invalid.
