Any segment voltages that were generated by direct mirror segment manipulation , will re-
main unchanged after homing Zernikes.
Note
Amplitude and Angle refer to the tilting function in the DMP40 which is not available for the
DMH40 due to absence of tilt arms. It is therefore grayed out.
4.6.6.1.1 Zernike Control of Higher Order
The sliders for Amplitude and Angle are grayed out
for the DMH40 because the DMH40 does not have
tilting arms like the DMP40.
The sliders for control of Zernike Z4 to Z15 allow a
predefined segment voltage pattern to be set up that
introduces a wavefront distortion described by the
selected Zernike coefficient. The sliders allow you to
change Zernikes within a control range that is limited
by the stroke of individual segments. Due to the de-
pendency on the optical setup, materials used in the
beam propagation path, and specific piezoelectric ef-
fects, the control range cannot be calibrated in abso-
lute values.
Control sliders and numerical inputs allow each
Zernike to be set within a relative range between -1
and +1.
In the closed loop control mode, the sliders show the correction of the mirror surface that is ne-
cessary to maintain a given wavefront.
Shifting the slider results in a coarse Zernike change. Alternatively, you can input the desired
value numerically. Finally, using the mouse scroll wheel (or cursor buttons), the slider value can
be changed with the following increments:
Increment
Ctrl + Mouse Wheel (
ßáâà
) 0.01
Mouse Wheel (
ßáâà
) 0.05
Shift+ Mouse Wheel (
ßáâà
) 0.1
Double click the Zernike name (e.g. "Z5 Def") to reset the appropriate Zernike to its home po-
sition.
Press the (Zernike Home) button to reset all Zernike sliders, including the Amplitude and
Angle sliders, to their home position.
Note
Resetting Zernike sliders to home position means that the appropriate 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.
