58 WFS Series
'Show Image Axes' displays the center axis in horizontal and vertical direction.
'Show Beam Diameter' displays a circle or an ellipse (light gray) that illustrates the
actual beam diameter and position.
'Show Pupil' displays a circle or an ellipse (magenta) that illustrates the actual pupil
size and position.
NOTE
Usually, there is a difference between the actual beam size and position and the
actual pupil size and position. Only in case you marked 'Use Beam Width' and 'Use
Beam Centroid' options within the Pupil Definitions Setup panel both
parameters coincide.
This display is also available for WFS10 instruments in Highspeed Mode with the
only difference, that the appropriate intensities are calculated within the camera's
DSP.

Wavefront Panel
The Wavefront panel contains a 3D diagram that displays the measured wavefront.
The wavefront data array is retrieved from the spot shifts which are directly
proportional to the local derivatives of the wavefront. A two-dimensional integration
process, starting at the center spot, leads to the wavefront data.
