DMH40
Indicate a file name and click the
Save
button. This way, a configuration can be used, for ex-
ample, to duplicate a setup or to save a configuration for future use.
Load
This menu item allows any user configuration file to be loaded. With this option, all application
settings and DMH40 data (Zernike slider positions and segment voltages) can be restored easi-
ly.
Note
With updating the Thorlabs Deformable Mirror software from older versions, the file structure
of the configuration files may have changed form .dmfd to .dmfc. The .dmfd files will not
readily be recognized by the new software version. Please follow the steps described in the
section
, loading .dmfd files.
Load ... Data (Zernike and Voltages) Only
Using this option, only
are loaded, while application settings remain unchanged. In this
case, only the Zernike and voltage data are retrieved from the selected .dfmc file.
Note
Loading data from a *.dfmc file just reproduces and applies the saved voltage pattern
and Zernike positions. Due to the piezoelectric properties (see
and
Creep of Piezoelectric Materials
), the surface shape generated by the
DMH40 will not exactly reproduce the original surface shape from the previous application of
these parameters!
Note
Data reconstruction will be correct only if the settings for Flip and Rotate are the same
as at the moment the data were saved.
Load ... Settings Only
In contrast to the previous function, here only application
are retrieved from the se-
lected *.dfmc file. Segment voltages and Zernike slider positions remain unchanged.
Close
The application will be closed.
Note
When closing the application, all settings and data will be saved automatically.
The MIRROR Control Menu
Cancel Segment Selection
deselects the selected seg-
ments, see section
.
Enable Index Overlay
is a toggle button to enable/disable
the numbering of the mirror segments.
Home Zernike
resets all Zernike sliders to the HOME posi-
tion. Please note that manipulating Zernikes applies a
voltage shift to all of the mirror segments related to this
Zernike coefficient. In other words, this is a voltage offset,
not an absolute voltage!
Resetting Zernike sliders to HOME position means that all Zernike coefficients are set to zero.
The voltage pattern on the mirror segments is generated accordingly.
Any segment voltages that were generated by
direct mirror segment manipulation
, will re-
main unchanged after homing Zernikes.
