Lightfield 4D Acquisition Always Uncompressed

Lightfield 4D images are always acquired uncompressed. To reduce the data size for Lightfield 4D images after acquisition, save them with Save As and select a compression.

Auto Save for Lightfield 4D Experiment

To set up Auto Save for your Lightfield 4D experiment, make sure to define the path in the Auto Save tool on the Acquisition tab. Set the path to a location on the SSD.

For high-speed acquisition, the images are saved in a temporary (tmp) folder in the Auto Save folder. After you save the fully acquired image, it is automatically removed from this tmp folder and stored in the selected location.

  1. You have set up one or more Lightfield 4D tracks, see Setting Up a Lightfield 4D Track without Smart Setup or Setting Up a Lightfield 4D Track with Smart Setup.
  1. To define the settings for your acquisition, use the tools on the Acquisition tab, for example by adapting the settings of the individual channels in the Channels tool.
  2. Your acquisition is set up.
  3. To define a time series experiment, Time Series has to be activated. It is automatically activated when you have added a Lightfield 4D track.
  4. The Time Series tool is available in the Multidimensional Acquisition section.
  5. Acquire with High Speed is automatically activated for all channels if all channels are using the same filter position in the reflector changer. Channels requiring different filter sets cannot be combined in a high-speed acquisition. If you have defined two or more Lightfield 4D tracks for multi-channel experiments, the exposure time for each channel is set the same. Updating the exposure time of one channel updates it for all defined Lightfield 4D channels. In this mode, the images from the camera are directly streamed to the hard drive (SSD) of the computer for maximal acquisition speed. It is not possible to set an interval.
  6. To define the duration and interval of your time series, open the Time Series tool.
  7. The time series is set up.
  8. To define positions for your experiment, see Defining a Lightfield 4D Multi-Position Experiment with the Tiles Advanced Setup or Defining a Lightfield 4D Multi-Position Experiment without the Tiles Advanced Setup.
  9. You have set up positions.
  10. Click Start Experiment.
  11. Your defined experiment starts, the image is displayed in the 2D view and the Lightfield 4D tab is displayed in the view options. The displayed image is the raw data image of the central lens.
  12. In case of high-speed acquisition, the update of the displayed image can contain a delay, as writing the data to the hard drive has a higher priority.
  13. In case you use Definite Focus and have configured your experiment to acquire with high speed, the Definite Focus is only executed before the time series starts and never during the high-speed acquisition.
  14. To display a specific time point during the experiment, go to the Dimensions tab and use the Time slider.
  15. The selected time point is displayed and the view is not updated based on experiment progress, Follow Acquisition is deactivated.
  16. To go back to an automated update of the image view, go to the Dimensions tab and reactivate Follow Acquisition.
  1. You have set up and started a Lightfield 4D experiment. Once the experiment is finished, the final image is displayed in ZEN.
