First / Last maximum
•
Click on the
First maximum
button to calculate the topography surface by using the first maximum
coming from the top.
•
This mode provides better result for surfaces of semitransparent materials with inclusions of higher
reflectivity or transparent multilayers with subsurface layers of higher signal intensity.
•
Click on the
Last maximum
button to calculate the topography surface by using the last maximum
coming from the top.
First / Last threshold
•
Click on the
First threshold
button to calculate
the topography surface by using the first slice
coming from the top, where the intensity
reaches the value defined by the lower intensity
threshold.

Click on
Z-Range…
to calculate the
topography surface by using the lower and the
upper height thresholds for image display. Use
of this function is recommended to get rid of
unwanted peaks and valleys taken into account
for parameter calculation. All topographic data
with height values less or higher than the
thresholds set are ignored for the display and
parameter calculation. This threshold applies
both for 2D as well as for 3D topography
display modes.
•
By clicking on the
Peak - valley
button the surface topography is displayed in that way that it is
automatically normalized to the lowest and highest Z value of the current 3D topography. Ticking the
check box
Automatic
means, that this procedure is continuously performed during further changes,
like application of different filters.
•
Set the
Threshold
to define the lower and upper intensity thresholds used for calculation of the
topography surface. Use of this function is recommended to find the real surface in the case of images
with pronounced noise. All image pixels with intensity less or higher than the thresholds set are
ignored for the surface calculation.
