Graphical User Interface (New)
The General Edition of DIFFRACT now comes with an optional Graphical
User Interface (GUI). The GUI allows the user to set up an optical
system by selecting objects from a menu and specifying their parameter
values in an interactive, user-friendly environment. Once the optical
system is set up, the GUI submits its Command.dat file to DIFFRACT and
waits for the simulation to run its course. Afterwards, GUI will access
the various graphics and data files created by DIFFRACT during the simulation,
displays the results, and enables the user to modify the setup, to put
the simulation through loops, and to plot the various signals recorded
in the Signals.dat file.
various features of DIFFRACT's Graphical User Interface also enable the
data files for constructing large and complex geometric-optical systems.
data files containing the Zernike aberration coefficients.
- Import interferometrically
measured, cross-sectional beam profiles from WYKO-compatible data files,
then save them in standard DIFFRACT format for later processing.
- Create amplitude/phase
masks from existing beam profiles, or from user-defined functions, then
save the mask files in standard DIFFRACT format.
- Extract the Zernike
aberration coefficients from the phase profile of imported beams.
- Create "sliced
masks" from continuous amplitude/phase profiles; useful for studying
segmented liquid crystal phase modulators.
DIFFRACT and its GUI are separate programs and can, in principle, function
independently of each other, in practice GUI acts as gateway to DIFFRACT
by facilitating the input/output of text and graphical information. In
the process, the simulation engine (DIFFRACT) remains invisible, while
its behind-the-scenes operation is fully controlled by an exchange of
information with the GUI.
more information about DIFFRACT's GUI, please download a (compressed)
copy of the Readme.doc file, which contains
instructions on how to set up and run the Limited Edition
of DIFFRACT 7.9. You may also download a free copy of DIFFRACT's Limited
Edition and its GUI by clicking on LimitedDiffGUI.ZIP,
then following the instructions provided in the Readme.doc file.
users of DIFFRACT 7.7 and 7.9 may purchase the Graphical User Interface
package and run their copy of DIFFRACT under the GUI. New users may order
DIFFRACT with or without the optional GUI, although a discount would apply
when DIFFRACT and its GUI are purchased together (see Pricing
and Service Policy).
