Measurement
and Analysis
PLµ software provides an interface with which any measurement (as roughness measurement...)
can easily be taken, as well a complete set of tools for displaying
and
analyzing data (as roughness parameters…).
Interactive 2D and 3D display options allow
one to switch between isometric, contour, profile, histogram,
bearing area and FFT, and to configure scale, zoom and color
scale. Profiles from topographies can
be defined as X, Y and skew cuts.
Analyses include advanced filtering, term
removal, volume assessment
and calculation of height, width and slope of surface features.
Cursor information and statistical parameters are always on
the screen.
A profile's waviness and roughness
parameters can be calculated. By way of example (left), the
roughness parameters of DIN standard are calculated for a
profile obtained from the topography of a calibration standard.

Profile
display |
Filtering of the profiles provides standard statistical parameters
for roughness and waviness. Data can be exported as ASCII or
raw files
that can be processed with most standard software packages.

Powered by OpenGL®
The 3D surfaces measured by PLµ
can be observed from different viewpoints. OpenGL® three-dimensional
graphics allow navigation
through the acquired topography, and the surface can be rotated,
moved and scaled by just dragging the mouse. The combination
of lighting
effects and the different color scales offers a quasi-photographic
impression. Axes can be disabled to increase the effective visible
area.

Data export
An export tool allows one to save measurement data as a text
or binary file. The display area can also be saved as an image
file (jpeg or bmp).
The PLµ file format is compatible with DigitalSurf MountainsMap
and
Mark III softwares.
