' 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.
4.3.2.5 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.
