pip install fringes-gui

Usage

You import the fringes-gui package and call the function run().

import fringes_gui as fgui
fgui.run()

Now the graphical user interface should appear:

Attributes

In the top left corner the attribute widget is located. It contains the parameter tree with which all the properties of the Fringes class from the fringes package can be controlled. Check out its website for more details. However, if you select a parameter and hover over it, a tool tip will appear containing the docstring of the respective property of the Fringes class.

The Visibility defines the type of user that should get access to the feature. It does not affect the functionality of the features but is used by the GUI to decide which features to display based on the current user level. The purpose is mainly to ensure that the GUI is not cluttered with information that is not intended at the current visibility level. The following criteria have been used for the assignment of the recommended visibility:

  • Beginner:
    Features that should be visible for all users via the GUI. This is the default visibility. The number of features with 'Beginner' visibility should be limited to all basic features so the GUI display is well-organized and easy to use.
  • Expert:
    Features that require a more in-depth knowledge of the system functionality. This is the preferred visibility level for all advanced features.
  • Guru:
    Advanced features that usually only people with a sound background in phase shifting can make good use of.
  • Experimental:
    New features that have not been tested yet and are likely to crash the system at some point.

Upon every parameter change, the complete parameter set of the Fringes instance is saved to the file .fringes.yaml in the user home directory. When the GUI starts again, the previous parameter set is loaded. To avoid this, just delete the config file or press the reset button in the Methods widget to restore the default parameter set.

Methods

In the bottem left corner you will find buttons for the associated methods of the Fringes class. Alternatively, you can use the keyboard shortcuts which are displayed when you hover over the buttons. The buttons are only active if the necessary data has been enoded, decoded or loaded.

Viewer

In the center resides the viewer. If float data is to be displayed, nan is replaced by zeros.

Data

In the top right corner the data widget is located. It lists the data which has been encoded, decoded or was loaded.

In order to keep the Parameter Tree consistent with the data, once a parameter has changed, certain data will be removed and also certain buttons will be deactivated. As a consequence, if you load data - e.g. the acquired (deflected) fringe pattern sequence - the first element of its videoshape has to match the parameter Frames in order to be able to decode it.

To display any datum listed in the table in the Viewer, simly select the name of it in the table.

Klick the Load button to choose a data or parameter set to load. With the Save button, all data including the parameter set are saved to the selected directory. Use the Clear all button to delete all data.

Please note: By default, the datum fringes is decoded. If you want to decode a datum with a different name (e.g. one that you just loaded), select its name in the table and klick Set data (to be decoded).

Log

The logging of the Fringes class is displayed here. The logging level can be set in the Parameter Tree.
