Spatial Light Modulator Display SDKAn updated version of the HOLOEYE SLM Display SDK for Python (Windows version) is now available. Updates are available trough our download website at https://customers.holoeye.com

The main new features are transform functionalities for scaling and shifting of the image, reposition and changing focus and functions to add Zernike polynomials.

New Features

  • Added transform functionality which allows you to shift and scale the data on the SLM.
  • Added beam manipulation functionality which allows you to reposition phase data as well as change the focus.
  • Added Zernike function to add Zernike overlays on your data.
  • Added button to the preview window which allows you to see the current Zernike radius, if one is set.
  • Added button to the preview window which allows you to edit the properties of the current handle for easier debugging
    and experimenting.
  • The initial preview window size is now based on the size of the used SLM.
  • Added more detailed timing information.
  • We added a wait function which handle the case that the SLM is closed while waiting.
  • The preview window can now be controlled from within your code.
  • Added logging for better error tracking.
  • Introduced a single function to apply values to a datahandle, for a lower overhead when setting multiple values.
  • Added functions to access SDK version information.
  • Added version check to make sure your code is compatible with the current API version.
  • Data is now only rendered again when the way it is displayed changed.
  • Added function which provides error strings as Unicode.
  • Added pitch support, to be more flexible with how data is aligned.

Bug Fixes

  • Improved error handling for when the process was not started.
  • The preview window now interpolates data when showing scaled data to show less artifacts. This does not affect the
    data shown on the SLM.
  • Showing datahandles again now correctly resets the related timers to have consistent timer values.

Known Issues

  • We currently do not support the GAEA-1 device under Linux.
  • Under Linux, the preview window shows a framerate 30Hz for 60Hz devices, but performs the 60Hz as expected.

Migration

  • We dropped support for Windows 7.
  • Please refer to our [migration guide](\ref migration) for more detailed instructions.
