Check the box to display the segment indices.
Enable Auto-Connect:
When set, the Thorlabs Deformable Mirror
software automatically connects to the first Deformable Mirror that
is recognized by the software after dis- and reconnecting. When
the box is not checked, the user needs to choose the Deformable
Mirror.
Zernike Pattern Orientation
The Thorlabs Deformable Mirror software calculations for closed
loop control depend on the optical setup, particularly how optical elements in the optical path
between the DMH40 surface and the wave front sensor influence the image orientation, or in
other words the Zernike pattern orientation. Mirrors and beam splitters flip the image. Also,
there may be a rotation between the XY axes of the DMH40 and the WFS. All this can be com-
pensated manually in this menu. The pattern can be flipped horizontally, vertically, or by a rota-
tion angle of 0°, 45°, 90° or 135°. Besides the manual correction, the Thorlabs Deformable Mir-
ror software is able to analyze the Zernike pattern orientation automatically - please see section
Control Loop Parameter Determination in the manual of the DMP40.
Note
Any changes that are made manually to
Zernike Pattern Orientation
in this panel will over-
come the results of the Control Loop Determination results! In other words, if you change
Flip
and/or
Rotate
after an automatic adjustment was carried out, the control loop will not work cor-
rectly.
Control Loop Adjustment
Control Step Delay is the delay time in milliseconds between setting a Zernike pattern for loop
control and retrieving the next data from the WFS via DataSocket.
