2 Measurement Results

Dependent on the selected analysis mode the parameters described in the fol-

lowing chapter are calculated by the spectro2profiler.

In order to optimize the measurement results for your specific structure the

2D / 3D settings can be edited in Standard Management of the "smart-chart"

software.

The firmware uses default settings, if not changed in Standard Management

and sent to the instrument with a specific standard.

2.1 Leather-like Structures

Cn - Number of Cells

The number of cells included into the data analysis. Incomplete border cells are

excluded from the data analysis.

Cs - Mean Cell Size (mm²)

The areas of the included cells are measured and the mean value is calculated.

Ca - Mean Cell Amplitude (P-µm)

The minimum height and the maximum height in each cell are detected. From

these two heights the amplitude of one cell is calculated. The averaged amp-

litudes of all cells yield the mean cell amplitude. The unit is perceived height

based on the measurement technology.

R - Mean Reflectivity (a.u.)

The mean value of the reflectivity data. This is an absolute measurement. The

value is calibrated with a matt white tile. This camera standard is provided as

accessory. The unit is non-standard and thus an arbitrary unit (a.u.).

Rc - Reflectivity Contrast

The topography data is separated into valleys and hills. The threshold height is

parameterized (see below). The algorithm calculates the two mean reflectivity

values for the area of valleys and of hills. The contrast is calculated with the

contrast formula contrast = (hill – valley) / (hill + valley).

Rh - Reflectivity on Hills (a.u.)

This is the mean reflectivity value for the area of hills.

Rv - Reflectivity in Valleys (a.u.)

This is the mean reflectivity value for the area of valleys.
